Wrong Size

I started out weating size 54 and now I am wearing a 34 in jeans. When I hold up those 34's to put them on I think there is no way, but they fit. Every now and then I will look at my legs or arms and not reccognize them as my own for a half a second. What is really great is to be working and see the veins and muscles popping out on my arms. I now wear a medium shirt, the same size as my son. His are a lot more loose on him.  pan head
