There are some things you should never risk. Those are things like a home for your family to live in. Some risks are just plain stupid. Mortgaging the family home to invest in a risky venture could be one of those stupid risks. List your priorities and risk those of lowest value to you first. Stupid risk can cause divorce and even a failure of your health. Don't risk your health to get wealth and then be willing to give up your wealth to get back your health. That's just stupid!
