when we hug each other, we activate oxytoxin, the feel good hormone, in our system. Some people have a very low oxytoxin setting which makes them very vulnerable to depression and low mode and feeling lonely. Someone I respect well, said that we are actually probably evolutionarily designed to receive 12 good hugs a day, so who manages that? I got two hugs today. My maximum since I started counting, is 7. Ask for hugs, receive hugs, give hugs. Try to make them last too, not a brief superficial one but a really heart felt one
