Expiration Dates

I cleaned out my kitchen cabinet today, tossing things that had passed their expiration dates.  Some had expired a few months or years ago.  The baking powder and baking soda had expired in 2013!! Obviously I don't do a lot of baking. It made me start thinking about what if we had expiration dates posted on the things we do.  Use the ability to run by a certain date, hold your urine until you get to a bathroom, little things like that.  Would we use that knowledge to take advantage of the things God gave us before they expired or would we let them sit on the shelf? I am going to try to use what is left of my abilities before my expiration date arrives.
