If you really think about it, you will discover an amazing number of life's situations which are inherently risky. Nearly everything someone does is some type of gambling. Even with such mundane act of getting up and going to work, increases one's probability of being killed in a transportation accident. In face of today and everything you know about investing, whether it be in business, an asset class (stocks, bonds, real-estate, cash and commodities), or trusted lotto dealers index fund, even in its most basic element, it's nothing but "betting" that someday tomorrow will probably be better with pleasant expected returns on investment; or even not. There is only one big risk you should avoid and that is the risk of doing nothing and not taking your chance.

Come to look-at it in face value, investing in almost any money market really is, legalized gambling, per se.
