One 'enthusiast' reckons that he has improved his vision and his oral health with one special secret ingredient - his own urine.
Weird flex, but OK...
The guy's name is Steven Williams and he runs his own YouTube channel on which he extols the virtue of gargling with his own piss. Oh, and he goes swimming with glasses full of wee as well.
Steven - who produced his own documentary about his lifestyle called Urine Aid - can be seen urinating into a cup and then rinsing out his eyes with it.
Now, Steven claims that it is really good for you. I mean, he's not a doctor, but whatever floats your boat.
He explained: "I've tried using aged urine with eye-droppers and I dropped them into my eyes.
"That really is quite painful, it stings a lot. But it's very effective for reducing cataracts and getting rid of things like that in the eyes... like styes.
"While we're talking restoring vision, I always get a little cup like this, fill it up with urine which I'll do now; a little bit of fresh urine.
"I prefer fresh urine, it makes dry eyes moist so it's great for dry eyes.
"Just hold the cup up, hold it over the eye and just start blinking. Roll around the eye, look up, and down and just do that for a few minutes.
"If it runs on your face don't panic because it's really good for the skin. Once you've finished I tend to throw it out and start a new batch for the following eye."
Sure, Steven. Whatever you say.
He continued: "When I'm at the swimming pool, what I do is fill up my goggles with urine," he admits.
"I sneak into the toilet. I pop it on my head like that which starts a little suction. And then when I'm in the pool I just slip them on to the top of my eyes like that.
"I pretty much do my laps and my eyes are getting a really good soaking. That's a good 10 to 15 minutes of dosing. So at that time I get a good wash-out and clean the eye out in that way."
Steven also goes into detail about how he gargles his own urine to whiten his teeth.
He added: "After about five to six minutes it gets a very lathery texture to it. You can feel it getting thicker. Sometimes I have to spit a little bit out just release the pressure in the mouth.
"And in about ten minutes, it is like soap. Really thick and foamy and lustrous.
"It's making my teeth smile whiter."
"You don't have to use a toothbrush, you don't have to use toothpaste. Three times a day, just a little bit of urine cleans my mouth."
Make what you will of that.
Despite what he thinks, not everyone is so convinced of the restorative and health giving powers of piss-swilling.
Leading pharmacist and Chemist 4 U founder Shamir Patel warned: "There is no scientific evidence backing up claims that drinking urine is beneficial.
"Urine is made up of fluid and waste products that your body no longer needs.
"When you empty your bladder, urine will exit your body through the urethra which can be home to some types of bacteria. Sometimes this bacteria can grow out of control and contaminate the urine.
"Drinking urine can introduce bacteria and toxins into your bloodstream. Pouring urine into the eyes can also introduce bacteria and toxins which could cause infection and damage vision."
Who are you going to believe?
