Very true. When you are young you have time, health, freedom to decide. But you dont have the wisdom to avoid mistakes and there are many dangers to get into shackles. For examlpe, you marry, buy a house with debt, work hard and disregard your own healthcare. So the diffuculty is how young people can achieve the wisdom and experience of the old. Of course this is not any stuff at school. Life has to be made forward, but can be understood only backwards. (Kierkegaard)
