Drinking your own urine is also a great survival technique. But it must be your own.
In many cases where multiple people were stranded and facing death from starvation
where people have died, it is almost always the ones who drank their own urine who
were the survivors. Even if you have plenty of water, the urine drinks will still survive
the longest.

Source? Well this isn't really new. Just try and find some reports on it.
