We've known each other for a long time in "internet-time" and know you have a healthy bone in that scalp of yours. There's no need to test that theory. You can always bend my ear.
Well my head has a lot of hard calluses on it from my bar room brawling days and work place accidents but it couldn't stop a bullet so I'm pretty sure your head couldn't stop a bullet ether. This might sound like bragging but once my head proved it was hard enough to stop a potato fired from a potato cannon. Cheers!
