I read a few posts on this earlier many of them touched base on facts and speculation. I think risk tolerance comes with age, simply the younger you are the more you should risk. If a person is older they have more to lose, and less time to ever make it back if your younger, well you can bounce back from a loss so some risk should be taken. Every once in a while something like Noront comes along something that can be a gamechanger in your own life. I don't have enough shares in Noront to retire even if it goes to $20.00 but what i have i'm willing to lose although i think that to be unlikely. What it will do is put me 5,10, mabe 15 years ahead of the game in life, i'm only thirty something i'm invested in risk here and there but i'm not putting it all on the line to retire next week or month instead i'm looking 10 years down the road which keeps my feet on the ground and my head out of the clouds and my risk tolerance higher! JMHO! GLTA!
