They go out of date so fast.I sometimes forget the one in my lunch box I carry at work when I go golfing.Dying is going to happen sometime from something.I try to be prepared but I still forget sometimes. I hate it..I used to consider them just an annoyance like a skeeter bite.Must of been stung at least 100 times before I became allergic. Sux a little bug can put you down like that.
