Query: Effective Way!

Now that I have rigorously applied this technique for over one hundred days I can safely say that I am happier than I've ever been in my life. Constricting my anus was at first tiresome, but after a while, I learned to really enjoy the practice. As an added benefit I've freed myself from tiresome, frustratingly long bowl movements. I can now pass even the largest of masses with ease, and most in only a few seconds. So I would have to say that this really is an effective way to regain one's sense of self worth and squeeze the life out of depression once and for all.
