> cycling is a physical activity that you can partake in well into old age. I'm not sure at what age it's no longer safe. Even when you are young, riding around a busy city with traffic can be a bit dangerous. Coordination decreases as you age, and at certain point, one fall can yield broken bones. A broken hip, for example, when you are old can be the beginning of a permanent decline.
