Retirement used to mean you could just kick back and relax. But now, thanks to the nature of the economy and longer life spans, that's become an elusive dream for many retirees. Maybe you need to earn extra cash, or you want to try your hand at an online job, or you're just tired of sitting around and want to stay active with something profitable.
There are plenty of earning opportunities for people in their retirement years, and I've rounded up several that are worth considering. Even if you haven't retired yet, these can be great side jobs for a stay-at-home mom, a teacher on summer break and plenty of others.
