Dear PTC,

What an excellent point to raise.  Washing your hands often at the gym makes abundant sense.

Now that I'm thinking about it I'm reminded of the antiseptic cloths many grocery stores offer to patrons for washing their hands and the handles of the grocery carts.  It might be a good idea to
wipe down the hand contact part of any exercise equipment you use.  

This may or may not be practical, but it's something to think about.
