When your age asserts itself

Woke up this morning feeling like heck. I am not surprised though. Last night at work I sorted our shipment of goods and some of those boxes are extremely heavy. By the time I was done my wrists, shoulders, neck and back were killing me. I seriously think that part of the job is getting beyond my comfort zone. Oh I can do it but the result is feeling like heck the next day. I woke up with a headache and it is still here. This is probably the result of strain on my neck from lifting and balancing the heavy boxes. It would be okay if I could just pull them off the stack and not have to lift them back up but there is only so much room. I really hate doing something and the whole while my brain is saying there is going to come a time when this is not going to be possible. Something happened to my wrists a while back and now I really can't hold or lift anything heavy with my hands where my wrists have to maintain stability. To take off the pressure on my wrists I use my shoulder to balance boxes until I can't get them down and that just wrecks my shoulder. Geez I am a mess.
