Turning 40

So this past weekend I turned 40 years old, now I'm certainly not a virgin but leaving my 30s feels ok because they were great and I look forward to my 40s. The only thing that scares me is I noticed my wife had a life insurance quotes sites bookmarked on our main laptop and I kinda got scared. We already have insurance is she planing to get more insurance and then off me or am I just getting paranoid in my old age. Maybe I'm just getting stir crazy because no golf courses are open yet and I'm getting the itch. Oh! I'm going to love my forties.
