Sorry Fantome I am not talking about mortality or the risk of disease.
If you have major cancer surgery we can measure the risk of dying from the operation itself. Muscle mass is a major determinator. This evidence is evolving but the only way we know to maintain muscle mass is regular exercise
Until a couple of years ago there was really no evidence exercise was beneficial except for rehab after a heart attack. The early work from the US was not scientific. So I find myself doing a 180 on the benefits of exercise.
Sorry to go off thread
