Use it or lose it

Use it or lose it is the message from this study. The elder person who maintains a high level of aerobic fitness will live longer.

A study looked at aerobic fitness in 2077 hypertensive men aged 70 or over. Overall mortality was 15% lower in those with moderate levels of aerobic fitness; 37% lower in higher levels of fitness. Many of us spend hours sitting through a day and this has a negative effect
