Would it be better to invest or pay down mortgage?

I think an even larger factor is what if you lose all of the money? If you have a very stable job that you are very very unlikely to lose and if you did you could get another one easily then invest the money. If you lose it you can still make your payments and live off of that.

Obviously nobody has that secure of a job nor are they necessarily able to handle the idea of losing all their money but I think the idea is still valid.
