I’m suffering a bit from yet another attempt to resolve the ongoing pain in the wrist I injured almost 5 years ago. See some previous posts for some of the details. So this will be a relatively short post. I admit that I took this photo several years ago at the Montreal Botanic Gardens. At … Continue reading
Someone asked me the difference between horns and antlers so I thought I’d make it a mini post. Horns, like those of the big horn sheep, have a bony core that grows from the skull and an outer layer of keratin which is the substance that makes your hair and nails. Horns are permanent and … Continue reading
This is an extra post this week in recognition of Bell’s Let’s Talk Day in Canada. I’m pretty diligent with my exercise and have been for most of my life. There have been times though when I’ve been criticized for this commitment. I distinctly remember one of my office mates during my PhD questioning me … Continue reading

I was going to do this post as a magic Monday until I read about all the people who have been burned doing this trick, so perhaps it is better left as one that you binge YouTube videos of. The trick is that you take boiling water outside in frigidly cold temperatures and toss the … Continue reading
When I was diagnosed with asthma as a kid, I remember someone saying that it wouldn’t go away unless I stopped skating because of the air quality in rinks. I was wondering what the research on this is. Rundell (2004) found that the pulmonary function, basically how well a person breaths, of a group of … Continue reading
I grew up figure skating, but I am also very comfortable on a pair of hockey skates. (Please don’t call them women’s vs men’s as this perpetuates stereotypes that just aren’t true.) When I taught learn-to skate lessons I was often asked about the differences between the two types of skates and when this question … Continue reading
