When you get into your 50's, unless you've won the genetic lottery, you need regular exercise or things will go badly wrong if you also have a tech industry workload. I nearly died ignoring that. Now I exercise every day, usually on my bike or a rowing ergometer. Less need for caffeine, better alertness. The time spent is returned in better productivity.
