> But exercise is a habit. If you don't build it up when you're young, it can be hard to develop it later.
That's not my observation. People over 40 I see practising regularly a sport activity are mostly newcomers who found there something they could find in their usual work and family life. Whereas those who practised as teens and young adults have often given up, because it is not compatible with their 'new' life; or because it is a symbol of their young days and they are done with it, they moved on; or because they cannot keep the same level of performance they had and they rather stop than underperform; or just because their sport activity broke them so that they are unable to practise it or any other form of sport any more, or they don't want to hear about it any more.
> And then there's the physical challenges of returning to a physically active life after years or decades of inactivity. Certain injuries are more likely (like back, knee, tendon injuries) which can be debilitating, leading to months of recovery and more sedentary behavior.
I have never seen an activity generating as many injuries as sport does (and especially school sport in my personal limited observations: more injuries in school sport session than in club training, and more injuries in club training than in actual matches. I find the latter surprising, but not the former.)
