Head or hair
While I was parking my vehicle in the parking lot of my office, another fellow employee drives in without a helmet and finds an empty spot right besides me to park his bike. The guard on duty comes in to remind the employee for the helmet. The educated employee of an MNC retorts back with an excuse that wearing helmet is having an adverse effect on his hair. He's losing his hair because of the use of helmet. P.S. It's okay to lose hair than lose head.
