Tests have proved that small babies can actually die from lack of human contact.Its horrible to hear of some orphaned babies fading away just because nobody holds them or talks to them. And look how little children love being picked up; being held on the laps of people that love them.
Mysteriously, people need affectionate touch.
And its a really easy way to affirm and strengthen a special relationship.
Doesn't cost anything
Not even energy
And it pays rich dividends
