How much do you exercise a day/week?
lowe: with exercise i've found benefit as a function of time to be crazy non-linear. there's a much bigger difference between 0 minutes and 20 minutes spent exercising than between 20 and 40 or 40 and 60. so when i'm busy, i do what i can, keep it short, but never cut it out. i try to do something every other day at least. it clears my head and resets my stress.i like to run. simple. no gym membership. no complicated/expensive gear -- only necessary investment is a pair of running shoes (runs around $90). best of all, you can exhaust yourself quickly: if you don't have much time to spare, just run faster* for less time.* i wouldn't recommend taking this to an extreme. i knew a guy in college who'd max out the treadmill for a few minutes, sweat like crazy and call it a day. odds are that's terrible for you.
