26 hours in two days

I'm seriously sore.  I've worked 26 hours in the past two days.  56 in the past five days.  I'm getting more flexibility in my arm.  I'm able to extend the Robocop Brace to the 60 degree setting and have that full range of motion now.  I feel guilty that there's so much work to be done moving things, but I can only sit there and direct traffic.  I'm only supposed to pick up things weighing less than three pounds.  That's not much.
