These men from Islington, London, claim they have not had a cold in almost 20 years, because every time they go to the toilet they snort a cup of their own wee.

Sam Cohen, 41-years-old, has used a cup to funnel wee into his nostrils every time he goes to the loo for the last 19 years and says he has never had a cold. The special needs teaching assistant claims it does wonders for his sex life and that it cures him of any illness.

Cohen and his friend Kelly Saliba, 48-years-old, are seen drinking their own urine by pressing their nostrils against wine glasses and inhaling the fluid through their nose.

Cohen describes why drinking urine is beneficial: "If you have a good diet and look after yourself then your urine is going to be the best, even if you're not so healthy then it's going to be very good for you."
