Fist-bumping the handshake

The handshake â?? a meet-and-greet fixture since medieval folks developed the gesture to show they werenâ??t armed â?? is beginning to be replaced in

Lightly tapping fists has been a staple of athletes for years, and now it is making its way into business circles. So far,
itâ??s used mainly by younger men who already know each other.

How do you feel about it? When does it work, and with whom?
