loneliness
For older australians or even for the young to combat loneliness all you need is a computer with a web cam.
That is what I did, and I met people from all over the world.
Just go onto a good chat site,you can start with texting, then if you like what you read then go onto emailing each other, then video chat where you can see each other. With email you can send photos and become very good friends, even visit each other if you like. You don't have to talk about sex, there are other things to talk about. All sorts of things.
It is like the old pen pal friendship but much better. Why not give it a go? It can be very rewarding and you can make good friends and beat loneliness.
Would like to know more deatails of how to do this John, sounds very interesting, not everyone is an expert on the computer (including me)
