The Torah tells us that men and women who are not related should not engage in any physical contact, no hugs, no handshakes, not even a high five.
Why is that?
The Torah tells us that physical contact between men and women is intimate, and therefore must be reserved for family only.
In the modern world we don’t see it that way. Today physical contact between the sexes has become mundane and commonplace. Men and women shake hands without giving it a second thought.
But that is not a good thing. We need more intimacy, not less.
The more intimacy we bring into the family, the healthier our families will be.
