yeah, that's right - elbows! how are your elbows?

my shirts always get holes in the elbows, from pivoting on my desk/arm rests all day, each day. that's usually what kills my work shirts (buttonup dress shirts) - a big hole in the elbow. does anyone else have this problem, or do you all work at home wearing t-shirts convered with cheeto and mountain dew stains?

i actually think my elbows look different...the skin seems to be a little darker. maybe some sort of long-tern, fabric burn calouses. thoughts?
