I guess you couldn't get my point. You are talking almost synonym what I said there.I doubt if you can find one. All medicine/chemicals have a bunch of effects on the body. What is happy if you are already dead of breast cancer?
I have already said one need to find it for it is hard to find, since I don't think there is one. I said happy for those guys who love using them not for people looking for a better and safer alternative than the presently available. Remember modern age comfort loving people hardly give any thought to side effect(s) thing when it comes to comfort and ease.
