@Robert Mitchum Stating the obvious here (I guess) but staying strong into old age is a great strategy for longevity and just being able to enjoy life. Dr. Gabrielle Lyons has a great quote about doctors wanting to know your weight, but never checking on, “How *strong* is my patient?” Also, apparently grip strength is correlated with longevity.
Lastly - my first rule for training/working out as an old guy is, “Don’t get hurt.” Getting injured wrecks the whole program…
