The findings do not mean that muscle building will make you live longer, experts caution

How muscular you are as a teenager may predict how long you live, at least if you are a man.

Swedish experts who tracked more than a million teenage boys for 24 years found those with low muscle strength - weaker leg and arm muscles and a limp grip - were at increased risk of early death.

The team behind the BMJ study believe muscle strength reflects general fitness, which would explain the link.

Experts stress the findings do not mean muscle building makes you live longer.

1. Difficult to interpret

That finding is difficult to interpret because a lot of things are associated with muscles. It could be men with high testosterone live longer but I don't believe there is any evidence of that. However, high energy and testosterone also associated with Human Growth Hormone which may relate to longevity. The authors could be right but there are a lot of alternative explanations.

3. Muscular teenagers

May be more likely to enjoy exercise or have it tied in with their identity, so more active as adults. And of course adults who exercise tend to live longer.
