3 Billion Rides

Sometimes the most bizarre thoughts will pop into my head. Which is probably no surprise to anyone. I realize that most people have weird ideas from time to time; they can't be original thoughts, either. Very few of those left in the world, I suspect.

I once heard or read that the human heart has the capacity for only so many beats. In an average 80 year lifespan it will beat about 3 billion times. Does that mean if you exercise a lot and increase your rate of heartbeats, you'll die sooner? Exercise strengthens the heart, so your resting heartrate will be lower, so the number of heartbeats will even out in the end (I think that's how it would work).

When you live with a diagnosis of MS and one of your symptoms is fatigue, you learn to pace yourself in your day to day activities. Come to think of it, sometimes week to week or month to month. You don't do laundry on the same day that you shop for groceries, for example.

So after Sunday's 21 k bike ride, I was thinking, "What if I have a finite number of long bike rides in me?" Say, 100. Do I get more and more fatigued with each ride until I've reached the finite number and can't ride any more?

Like I said at the beginning, bizarre thought. However, after mulling it over, I think I've rationalized it to this: Each ride will build my physical strength. The exercise is good for both body and brain (increased oxygenation, better circulation of nutrients). My eating habits have improved, so my nutrition is better, and my overall health is improving. And I know that if my overall health is good, my brain is better able to deal with the MS. So if I hit a wall from fatigue, taking a day or 3 or 4 off is not going to set me back. I can get back on the bike and do a couple of shorter rides, then a big one again. After all, marathon runners don't run a marathon every day for training.

I suspect a day will come when a genetic test will determine what number of heartbeats a person is predetermined to have. A full screening at birth will tell us if we are destined to live to 100 or 25. 10 years ago the average lifespan for a person with cystic fibrosis was 18 years. Today it is 35 (last year I met a CF patient who was 40). We will be able to determine and treat conditions in order to extend lifespans; actually, we already do that to a degree. If we are diagnosed with a treatable disease, we take medicines or alter our lifestyle to enable us to not be as affected by our disease. But a day will come when we find out at birth (if not prenatally).

So how many long bike rides do I have in me? Ask me when I'm 80.

Porcupine Crossing

Gas stations are great places to find bugs. They have these really big lights that are on at night attracting all sort of insect. Yesterday morning I raided the local station and retrieved a polyphemus and an azalea sphinx. Just beautiful specimens - which are now napping in my freezer until tomorrow when I will preserve them for posterity (actually, for my own amusement and study). Pics in the very near future, dear reader.

Today, the Wookie and I went on a 21 k ride, half on a trail, the other half back to the car on the highway. On the trail, I nearly ran over a porcupine that hadn't looked both ways before attempting to cross. It waddled off into the trees while I stopped to get my camera. I managed a few shots of it in the tree. These adorable animals have poor eyesight and not great hearing; they don't really need those senses too much anyway, what with all the sharp pointy things sticking out of their fur. Anyway, I had to get a pic for Lisa (I think), who last year was disappointed that I hadn't posted a pic of the one crossing a street that I had stopped for.



We left the trail just short of the end as I could see the ocean down a drive that crossed the trail and wanted to be next to the water. It was about 2k on that road to the main highway, then 9 more to the car. I took a couple of pics of the beach on one side, and pics of a fresh water marsh on the other side of the road. The marsh had several pitcher plants and a few clumps of blue flag irises. I had noticed both plants along the trail as well, though not as many pitcher plants (they are a protected species).




All in all it was a good ride, lots of sweat dripping everywhere and a few drops of rain from time to time to tease us. I was wishing the skies would just open up to cool us down. Then off to mom and dad's to wish a dad a Happy Pappy Day. He was happy with the gifts, of course. "Don't be spending your money on me" is a quote to be ignored.

I'm Here!!

I have been amazingly lax the past few weeks as far as the blog goes. You should go make yourself a cup of tea before you sit down to read the rest of this post.

I really have put the push on for getting donations for the Bike Tour since I don't have the support of a "work" network this time 'round. So that's been keeping me hopping. Though I did have one really good experience at the grocery store last week. A man in line in front of me commented on the bike tour jacket I wear and asked if I did the bike tour. Turns out he had been invited to participate with some friends but is unable to do so. I told him he could help out just the same by sponsoring me. So he found a bank machine to get some money to give me. I took down his name and address of course so he can get a tax receipt, but while waiting at the bank machine I told him I felt like I was shaking him down. He laughed, gave me 20 bucks and next year he may bike with my team instead of his friend's.

I have been in "serious" training for the tour as well. I have made a few short but heavy duty rides, lots of hills to work the legs. I am very pleased with my progress, getting up these hills with fewer stops, increasing my kilometres per hour average, and generally building strength in my legs. I have also fallen off the bike twice in the past 3 weeks, both times (as usual, actually) when I was coming to a stop. Last Sunday I'm afraid the spill I took drew a little more blood than usual, and two little boys watched intently as I administered my own first aid. The older of the two had questions for me about my "boo boo" and asked me to show him my other ones (after he showed me his). They were too cute for words and their mother pointed out the fact that I had a first aid kit with me which she informed them is always a good idea when going on a long bike ride. Come to think of it, it's a good idea for me to always have a first aid kit....I had to replenish my first aid supplies after the ride.

I took my bike in yesterday for its 1000k tune up. When the guy working at the shop saw me, I just showed him my bandaged knee and he said, "Again?". They put a new chain on the bike and tuned it up for me, as well, they have checked my pedal clips and hopefully loosened them (that's why I fall - can't get unclipped fast enough).

A couple of weeks ago, the majority of Canadian MS Walks were held. The Wookie, Margo, Marc, and I walked as a team, going 8 kilometres by foot. I had hoped to have a team picture to show you by now, but don't so you'll just have to wait. It was definitely fun and good to catch up with a number of people including the Sackville Kinsmen Club who are holding their car show again this year and asked me to set my bike up again. That's on the 27th.

About a week ago, one of the local tv stations ran a story about a local woman who is trying to raise money so she can go overseas and get the "liberation" treatment. Don't get me started. but what irked me was that she yanked her team from the MS Walk in protest of the fact that the MS Society is not lobbying the government to pay for this procedure. That angered me more than anything else I've heard recently. The MS Society of Canada along with the NMSS in the US has designated 2.4 millions dollars to study CCSVI and the link it appears to have with MS (this was announced just last week). It will not be funding surgical procedures at this point because we don't know if there is a link between the two. Depending on the outcome of these initial studies, then perhaps the "liberation" procedure itself will be studied.

The media still hasn't caught on to the fact that the theory behind CCSVI is that a build up of iron in the brain because of closed off veins is what causes MS. If there are iron deposits in the brain it would take more than half an hour to clear them from the brain, but half an hour seems to be the length of time between having the procedure performed and noticing a difference in MS symptoms.

So why do some people report miraculous results from this procedure? There are a number of factors at play including the Placebo Effect, not to mention improved circulation of blood in the brain. We all know that improving the circulation of blood in the brain is going to be good for you. My thoughts about miraculous improvements all involve improving oxygenation and toxin removal (by toxin, I mean cellular byproducts like waste). So until the folks who have had the procedure done can show measured reduction in MS symptoms over a period of time, I stand by my idea that this treatment is not an effectual one. Not for MS, anyway. It may be an effectual treatment for a vascular condition that many people without MS have. I would love to have this treatment proven to be an effective one for MS. But you must show me the scientific evidence first.

A couple of days ago, I was one of three people on a panel for a presentation to a group of health professionals about what it's like to be a research participant. It was part of a series of lunch hour sessions set up for health workers in the Capital District Health Association (which covers all of Halifax and surrounding areas). It was teleconferenced to other sites as well in 4 or 5 other hospitals. Most of the questions had to do with how we felt as "guinea pigs", why we agreed to be in a clinical study and our likes and dislikes about the experience. All three of us were quite positive about our feelings and how we were treated. Learning why we participated was important for these folks to hear as it helps them determine how to ask future participants to be in studies. It was a very cool experience for me as I had never really given any thought to other participants' reasons for being in a study, only mine; I'm curious, I need to know stuff (which they thought was funny). One panelist was given a drug in a different form that was being measured to see if it was more effective or just as effective as it's regular form. The other panelist was in a similar type study. In my case, in my first trial, this was one of the first disease modifying drugs (the other being Copaxone) for MS. Plus, I was in a Phase 3 trial which had the chance of me being on a placebo. The other studies have involved the course of my MS or looking for genetic markers, so have involved MRIs and blood work (both now a walk in the park for me).

And finally, on the bug front, it's almost SUMMERTIME!! Which means warmer evenings and lots of night time bugs. Like june bugs, face down on the pavement trying to drill their way to China. Or carrion beetles searching for meals. Or moths beating themselves against the building under the security lights - picture me below the lights after dark with my net in hand just waiting for them to get within reach. I retrieved a beautiful hawk moth last night which spent the day in my freezer. Taking a nap. In a couple of days I'll take him out, photograph him and preserve him. Pictures will be up before too long of my latest finds.

I promise not to be so lax from now on. Really.

Hip Hop as Intellectual Stimulation and More CSI:Bugs

Today on CSI:Bugs we have two cases. The first involves an apparent accidental overdose - of pollen. I first spotted this beetle in a tulip trying to escape up the sides of the flower. When I went back a few minutes later with the camera, it was gone. But a third inspection a day later revealed the creature(or one like it) had returned to the tulip and died there. The flower was now a crime scene.

I removed the body for closer inspection (of course) and found a very pretty substance covering most of the insect:



At 60 X magnification, the substance appears to be pollen:

As there was no evidence of use of force (no broken legs or antennae), it was concluded that the beetle died after covering itself in pollen (perhaps interfering with the animal's ability to fly) and then was trapped in the closing petals of the flower at night. Unable to find a warmer spot it froze to death (it has the same appearance of bugs I have deliberately frozen - for scientific seasons). Not really an overdose of pollen, but if it hadn't returned it might have lived.

The second case is still an ongoing investigation. In the front of the building we have a plastic container that holds a garden hose and nozzles for the hose. I open it up on a regular basis and have on more than one occasion removed some wasp, bee, or other bug from inside. Today, a mother paper wasp was in there tending to her nest. She had already made 12-14 hexagonal cells and placed a number of eggs in them and was preparing to make more. Not wanting to be stung this summer while retrieving gardening tools, I gently nudged the mother out (luckily she was woozy from the cold) and removed the under-construction nest:



At 60 X magnification:


I toyed with the idea of raising these babies on my own, but soon realized in a few weeks I will have about 10 hungry larvae demanding bits of caterpillar and other insects for breakfast, lunch, and dinner. What I will do instead is watch the eggs until they hatch into larvae, take some pics and then release them next to an ant hill. This will be a bit of an experiment to see if the ants will take them. The paper wasp secretes a substance on the stalk of the nest (the stalk is the bit that attaches the nest to a structure from which it hangs) and sometimes on the cells. It is apparently an ant deterrent and protects the larvae from being carried away when the mom's not around. If the ants aren't interested in them, then we'll know that the stuff works. If the ants carry them away, then it means that the substance must be regularly applied.

Since I have kidnapped the larvae, and none are dead yet, then the case is ongoing.

Cool, eh?

On a completely different topic, I received an e-mail from my high school friend, Welli. She's a married mom of two teenage boys and she recently started taking hip hop dance classes. She told me it's one of the most intellectually stimulating things she's done in a few years. On the surface that might seem a bit bizarre to hear. After all, Welli is one of the most intelligent people I've ever known and she has a career that required a great deal of education. As well, a lot of hip hop music is lost on our generation (actually, every generation has its own types of music lost on others). So why is this type of dancing so intellectually stimulating?
Welli says learning the steps and routines has been a workout for her mind. And that's the key. I have been extolling the virtues of stimulating your mind while you exercise. Simply going through the motions is not enough to maintain or improve brain fitness. Your brain thrives on novel experiences; that's why I tell you to change up your exercise routine, take different routes on your runs or rides or walks, listen to different music or books or radio stations while you do it (not while riding a bike though, that's not safe), even mixing up the exercises you do. Lately, I have been stepping up onto and over the boulders that line one of the paths I regularly walk. This takes concentration and making judgments about where to put my feet at the same time that it is using different muscle sets than just walking. I am also climbing and walking along benches and hanging from monkey bars on my walks. It is the new, different or novel things that our brain pays attention to and those are the things that increase the number of neurons. That is brain fitness. And that is why a hip hop class can be an intellectual stimulator.

Thanks, Welli.

CSI:Bugs

I have been negligent of late, not keeping everyone up to speed on what's going on. Thing is, I'm spending a lot of time just waiting for people. Waiting for the gov't to decide if they'll support me while I go to school. Waiting for people to show up for appointments to view an apartment. Waiting for service people to show up to service a broken appliance. Etc.

I could write about my experiences as the female Schneider (a reference to One Day at a Time), but I know that might get me into trouble. Let's just say that when this part of my life is done, I'll be able to write a couple of books about human behaviour. It's interesting and aggravating at the same time and I'll leave it at that.

A couple of weeks ago, I began riding my bike in earnest in preparation for the MS Bike Tour in July. As you know, I've been doing a lot of walking and hiking (and now, biking), yet when the Wookie came out with me on the weekend for a bike ride (after not truly exercising for months) he whizzed past me like there was no tomorrow, leaving me in his dust. On Sunday, I was in tears at the end of our short (7k) ride, frustrated because I was so tired and the Wookie was just fine. My legs were weak, had been the day before as well. Anyway, I pulled it together and we did a nice 10k ride the next day. Lucky for me, my meltdowns are few and far between.

I have been outside a lot, scouting for bugs of course, and being rewarded. Some of them I rush inside to go under the microscope, while others (like the ants) I leave outside and mess with their tiny minds. I find a line of ants, and try to rub out the scent trail, then watch them try to figure out how to get home again. They always do, after a moment's hesitation. Or I push a little sand into one of their entrances and watch them clean it out.

Then there are the dead bugs I find. That got me thinking about CSI:Bugs. This june bug met an interesting end:


It's missing it's head! Wait, there it is, 15 feet away and 3 feet off the ground. Seriously, it's on the top of the lamp pillar in front of the building.


Not having the capacity to do DNA analysis, I will never solve this particular murder. I do suspect it was at the hand of a human, though, as the bug was not eaten. Here's how I think it went down: the bug was flying around the entrance to the building, attracted by the light. A tenant comes along and walks into its flight path causing a reflexive swat by the tenant. The swat is so fast it results in the decapitation of the june bug. Now picture all that in slow motion with the appropriate "Ewwww" and "Gross" as the tenant hits the bug and the accompanying clicking sound as the hard shelled body hits the front walkway and the head hits the cement light pillar.

Oh! And I have begun my fundraising for the bike tour. The link to contribute is on the right.

Bug P*rn

Sadly, the mystery has not been solved about those vein like things on the underside of my june bug. They may be fungal in origin according to the curator of zoology at the local museum, but he would need a look see at the animal itself. That isn't possible as I set the critter free the next morning.

I did take some pictures today, though of some lady bugs (ahem) doing it.



Nothing like having the word p*rn in your blog post title to drive up readership....

What Is This?



Click on the video to see the underside of a june bug as its muscles contract. I don't know what the vein-like structure is, but I do have an enquery in to the local museum.

Here it is the middle of May and we're seeing these bugs already. We've had an extraordinary spring for this part of the world and gardens are in full swing. Most folks I've talked to feel we're 2-3 weeks ahead of normal as far as plants and wildlife go.

It's been a rather hectic two weeks. Last weekend of course, in Canada, we have the MS Carnation Campaign plus it was Mother's Day (hi Mom!). I've been out biking to get ready for the bike tour in July and the MS Walk is at the end of this month. And I'm trying to get things straightened away with he government so I can return to school in the fall...whew.

Anyway, I hope to be back to regularly scheduled posts about bugs, bikes, and brains in the next few weeks. The Wookie and I did attend a lecture last night about Genetics and MS (just more reason for my mother to feel guilty). On Sunday, my Mom and I are guest speakers at a monthly meeting of the local CWL(Catholic Women's League). We'll be talking about MS and how it's affected us, our relationship, and how we've coped (or not).

See ya' soon!
