I had one, all five years I worked full time. At the time I was married and figured the money would go to my husband. Now that I have kids, maybe it will go to them. (but right now my husband is the beneficiary) I contributed 10% and my employer matched some of that. I say go for it because you never know how long you're going to be around and it might benefit you, personally, someday. Anytime you can put away pre-tax dollars it's always in your favor. Some people say, "well, I'll just save the money somewhere else on my own" but I'm a firm believer in you won't miss what you never had. You never see the money in your checking account, it's like it was never there. For me, it's the easiest way to save. I hope your employer is matching some of it, that makes it even more beneficial.
