I don't run unless someone's chasing me.
My main exercise is pushing a grocery cart around Walmart at speed once every three weeks, usually on a Sunday at 7 AM when all the Jesusists are getting ready for church. Missed it yesterday because the ATT guy was coming to fix my wifi. Went today at 10AM, what a zoo! Almost ran over three fat slobs debating how best to clog their arteries with their four favorite food groups: sugar, salt, fat, and preservatives.
I weigh 132 lbs, 66 kilos, same as weighed 40 years ago and I wear the same 29 inch waist skinny jeans. When I move I do so quickly and there are no chairs in my house or shop. I'm either on my feet or reclining (as I am now.)
Sitting, it's the new smoking.
