Many physical sports are actually just great for 40+ folks, that&#x27;s why there are &quot;masters&quot; categories in competitions.<p>As long as individuals recognize the limitations of their age groups they&#x27;ll be just fine.<p>Actually, even if individuals _don&#x27;t_ recognize their age limitations and play against 20-somethings that&#x27;s also OK (if they&#x27;re willing to have their ass handed to them on every competition).
