Water, water everywhere

A comment from Sandra in BAS:UW:1 points out the value of water. Yes! Water is great. I think most people could benefit from drinking more water each day, especially those who are exercising.

Research published in the Journal of Clinical Endocrinology and Metabolism (is your subscription up to date?) even suggests that drinking water can actually help you lose weight! Something about water-induced thermogenesis:

In 14 healthy, normal-weight subjects (seven men and seven women), we assessed the effect of drinking 500 ml of water on energy expenditure and substrate oxidation rates by using whole-room indirect calorimetry. The effect of water drinking on adipose tissue metabolism was assessed with the microdialysis technique. Drinking 500 ml of water increased metabolic rate by 30%. The increase occurred within 10 min and reached a maximum after 30-40 min.

Of course, that's just one paper, and research published in the same journal earlier this month seems to contradict the findings.

Now, some people go overboard with the water. You've certainly heard the "rule" that you need to drink 8-10 glasses of water a day in order to maintain good health. Well, baloney. Snopes.com, the Urban Legends Reference Pages, debunks that myth. Furthermore, a Dartmouth Medical School study published in the American Journal of Physiology gives medical debunking to the "8x8" dogma -- eight glasses of water at eight ounces each:

the notion may have started when the Food and Nutrition Board of the National Research Council recommended approximately "1 milliliter of water for each calorie of food," which would amount to roughly two to two-and-a-half quarts per day (64 to 80 ounces). Although in its next sentence, the Board stated "most of this quantity is contained in prepared foods," that last sentence may have been missed, so that the recommendation was erroneously interpreted as how much water one should drink each day.


So, in addition to all my beverage consumption, I think the extra 500-750mL of water I'm consuming during the day is enough to keep me hummin'. My hourly (or more) bathroom trips seem to bear that out.

  1. Hey scott... I think your hourly bathroom breaks have more to do with a little puff... than a little pee.

A request, as we reach two years

Wow, long time no write.

I didn't enjoy this past winter. I was certainly in a long slump. Things were very challenging at work. Gordon was awesome, as always, but I was just in a sustained funk from last summer on. And I'm not sure I'm all the way out of it yet. I'm still largely in quiet hermit mode, but have been making progress at resuming social contact. Little dude and I have a very busy summer that will go by in a flash.

This Thursday will mark two years since Amanda died. I still replay the events of that night in my head almost every day. I'd like to not. Sometimes it feels like forever ago, but sometimes I'm right there all over again.

Hey, can I ask for your help with something?

Two years ago, so many wonderful people told me that if there was anything they could do to help .... Well, I don't ask often. And I should've asked more. And I should ask more even now. I'm still not comfortable asking. But I'm asking for this.

I put out a vi…

Hard to believe it's been a year - but it has

One year ago today, we lost Amanda.

Time plays tricks on all of us. We can think "that was so long ago" at the same time as "it feels like yesterday." I run into this all the time with Amanda's death.

Yes, it feels like just yesterday, or last night, or later today, that Amanda collapsed in the kitchen and died after that long, brutal battle with ovarian cancer. But every day has ticked by at a pace like any other, and it's been a whole year of those days, with incremental and sometimes revolutionary change.

As I move about our home, it's hard to fathom that she's been gone a whole year.

Many of the decorative items she carefully arranged throughout the house are in the exact same place as the last time she touched them. She had the vision, not me, so I've been reluctant to disturb her decisions on what looks good and works.

In other places, I'm reminded that it's been at least a year since something's been in place. Like the fully-s…

Amanda's cancer has returned, just months after treatment

It's been two and a half months since the last update on this blog, and I was hoping to write one soon with lots of good news.

I was going to write about our recent trip to Jamaica, where we got to go snorkeling, bake in the sun and meet nice people from around Canada and the USA.
I was going to write about how Gordon is now 11 months old and exceeding all our hopes. He's a little dynamo who's not that little -- out of 100 babies his age, no normal one would be bigger. He's spectacular and we love him to bits.


I was going to write about putting the finishing touches on the Twin City Wrestling TV show that I've been working on for the past several months. It's just about ready to be sent in to the broadcaster, and it looks great.
I was going to write about the Canadian Cancer Society using our story in a very moving fundraising letter for their winter campaign in Nova Scotia.
I was going to write about Amanda's trip to Toronto to learn about how Prince Marga…
