Besides, "it's sterile and I like the taste."
Of your own urine? Whew, quaxo, get some counseling, dude! Is this something you picked up in Thailand?
And the cow tipping, now that's a myth, as I know very well having grown up on a dairy farm. But, if you want a reference, see

My grandmother is 80 years old. She's still running an old Pentium that I had years and years ago. It has 256MB RAM and runs Windows 98. Do I need to give her an upgrade to XP, Vista, or 7? Why would I? All she does is email on it (seriously, she only has Juno email, no internet service). She knows exactly how to do the things she needs to do on it and that's all that matters to her.
My mother is 84. Her first computer had Win 98SE. She's been using Win XP for about 2 years now, as I recall, on a older computer given to her. And, she's talking about getting a new computer. When she does, it will, of course, have Win 7, and I have no expectation that she'll be asking for a downgrade of her OS. Of course, she'll have questions about Win 7 but I think we can work through that. Her transition from Win 98SE to Win XP was not terribly difficult and I don't expect that a transition to Win 7 will be so either.
