I think taking high risk in trading or investment has nothing to do with age, some people by nature are inclined towards gambling to get quick rich but  my learning through experince and life time observation taught me a clear lessson that  such adventures eventually end up in disaster with some exception when they win becuase luck is on their side. Risk managment is a science and we should learn it before jumping into any kind of trading and i can say with confidence you will win most of the time when you follow it.
