I think the thing about aging is that you have less energy, so you're less likely to make energetic mistakes, and more likely to take some calm moments to think things thru. also, if you have moderate ambitions and desires, with time you may reach a point where you've met them. Then you are less focused on those for happiness. so I do think age has something to do with it
