It’s really nice that you’ve survived these last 3 months. I really sincerely hope you are one of the lucky ones that make it.
Jan, it has nothing to do with luck. It is all the benefits of exercise. At age 81 my balance feels so good I could join a ballet class and not be laughed out of the class.
And the 2nd conclusion I have reached is one does not need to become weak and feeble with porous bones which fracture easily, with age. Regular exercise is the key to avoiding old age problems.
