Life really is what you make of it. You will find heaps of "real" people just depends on where you look really.
I think the more you fall into a defined roll, the more you find plastic people, but the more often you break out of your mold, and damn the consequences, the more real people will be with you. Shake em up a little bit and see what falls out!
Life is always worth living.
Always changing, different and full of uncertainties.
What else is needed to attract attention and interest!
Do you care that most people are plastic? Live for yourself, not others.
If you have that attitude, then don't bother. If you're not grateful for the life you've been given, why live it?
