That should tell you that you have been doing something right.
I know what SO means but I would not take it that far. Hell when I was younger and worked physical jobs I could not recover doing over 2 days a week and about 3 lifts each day. Many folks on these boards our age and younger do not do more than 1-2 or 3 lifts a day. There are exceptions but they are not in your work situation.(at least the two I am thinking of). Almost every time I try to lift in a state of fatigue it does not go as planned. A mental and physical lessening of overall load could help.
