They're really talking about getting rid of the handshake. A gesture pretty much everyone I know grew up using as a respectful greeting. Because we're all afraid of germs.
Here's a tip...wash your hands with soap & water. Anything that washing in that fashion won't kill, well, it'll get you sooner or later anyway.
The only reason the handshake shouldn't be used is if you have one of those gross limp-handed shakes. You people know who you are...and you should be ashamed!!
