I must be one of those people Linus wants to kick. Too bad for him. I love taking a break from staring at a screen, and I feel way better, physically and mentally, after a good run or a good rowing session. My lower back starts to feel stiff and cramped if I go for more than a day or so without exercise. Also, I can't imagine life without skiing, and that requires a pretty decent degree of fitness. Anyone who doesn't…
Disclaimer: These are, of course, just my opinions. I've been skiing for 10 or 11 years and snowboarding for 4 or 5 years.
