It's not fun to find out about bitter huggers who are trying to spread AIDS and other mysterious diseases through hugs. They haven't realized that hugs don't work that way (so, hugging doesn't spread diseases but positive attitude towards living).
The world may heal a little bit if hugging increases, but increasing hugging doesn't mean that the population is going to increase by the side. Hugging may involve sexual attraction but it's not the purpose of it either. The motives for hugging must be something a whole lot more valuable. The one whom you hug must be able to trust you and believe in your honesty about your pure motives. Be honest, be real and you on the right way.
On the right way you don't have to consider safety hugging (the picture)!!!
