Do you think there would be more acceptance and communication if people would be more open to touch?

This thought has come up from a series of questions asked on fluther. None imparticualar I care to mention. But it seems to me that many people would benefit from human contact, not just computers, ipods, and cell phones. I mean we are pack animals for heaven sake. We love sex, kissing, going out and hanging with buddies. But in all that time many many many people will not touch another without fear of what others thing. Something is wrong with that. Should we start touching? Ex: Handshakes, Hugs, Kisses, Dancing etc.
