My neighbour is 20 years younger than me, but some would not believe it!
I don't work out in a gym but I can still get off a low sofa without using my arms, bend down to pick things up, squat for a couple of minutes and get up without a push-up, have a good sense of balance andbother things. Why? Because I don't let others do for me those things I can do myself - fitness by doing! Stamina is another thing, my heart condition and a couple of inactive years can be blamed for that. Slowly re-conditioning.
Though, because I recently ran out of my vascodilator capsules for two days, my BP went up (to a whole 105/65) and I felt better. Now with a new supply I have cut the dose from 2 to 1 a day to see what happens. A walk round town later might show something interesting.
