Mark on the Wall Exercise

The wooden chair used as a desk for students attending Wabash College the home of the ''Little Giants'' So many essays and notes must have been taken on these chair/desks how old are they? Around ten years Im guessing, maybe older we need some new ones though because these are extremely uncomfortable especially for long tuesday thursday classes The wooden chair/desk that makes your back ache pains me every class with its harsh seating none of this makes any sense to me and is probably one of the more uncomfortable exercises I have done uncomfortable just like the wooden chair/desks that I sit in ever tuesday  and thursday.
