weary

I feel old. Today I just feel really old, and tired. I am not sure of the root of it, just an over-all mental and physical exhaustion. The bike ride yesterday in 40 degree heat may have some part in it, as I am sure, does the muscle relaxant before bed last night, but even more than that I jeust feel burnt out. There is no real reason for me to be feeling this way that I can pin-point. I guess my mind is working in overdrive mode, even when I am unaware that it is happening.
