Saving for retirement isn't a hard idea to grasp -- save money while you have it, so you can build up savings for when you're no longer working. Yet, the idea of saving for the future is lost on many young people. A recent study found that, starting with the baby boomers, the percentage of savings per generation starts to dwindle about 10 percent each generation [source: The Wall Street Journal]. Not only does this leave many ill prepared for retirement, it leaves them without proper savings for the unexpected. Bills for medical emergencies, life-changing events, hurricanes and other surprises can easily force someone with inadequate savings into debt.
