Life Expectancy of Home Components

I hope everyone's Thanksgiving went well.

I just found this handy 19-page guide that details the life expectancy of various home systems and features. It was created by the NAHB with funding from Bank of America, and it is very encompassing. I didn't come across any real surprises, but this is a nice guide to have if you're vacillating between fixing something or just replacing it. Have a read, and save it for future reference.
