The splashback scandal: should all men sit down to urinate?

"A while back, using a urination simulator and high-speed cameras, [Tadd Truscott] and a colleague did an investigation into “splashback” caused by urination, which he presented at the 66th annual meeting of the American Physical Society’s Division of Fluid Dynamics in 2013."

"Pee in general is very sterile. It’s not really a big deal if it lands on your toothbrush and you brush your teeth then. But droplets are quite capable of harbouring bacteria, and in the toilet this is a problem if you’ve just used the restroom for something else. There can be faeces in there – urea is a wonderful harbinger of E coli growth – so later in the day it might not be safe to use your toothbrush."

"Lionel Messi, probably the greatest footballer of all time, admitted to sitting to pee on a Uruguayan TV show called Por La Camiseta (For the T-shirt). Messi by name, not so in the bathroom."
