What is important?

Judging from my facebook list of friends one of the most important things is exercise. Yes, exercise, as in moving yourself regularly, is important, but all the guilt I see from people about not doing any exercise that day ... I just want to shout to them: People may die this day! You may die! Don't waste time on guilt, live! Talk to your friends, do things that make you happy, do things with your kids, have a cup of tea, sing if that's what you want to do! But don't waste time on feeling guilty for not exercising every day.
