I don't think there is any other reason that I can think of other than getting old. I thought Diet Coke was making me forgetful and making my bones ache. Well I stopped drinking it about 2 weeks ago and nothing has changed. I've been whining that I wanted snow and cold weather so we could go out and play. Well it's here now and I'm whining it's too cold. It must be old age! I'm 39!
