They outlived what most people expected.

Dying at 68 in 2020, they made it into the Guinness Book of World Records for their lifespan, living six years longer than Chang and Eng Bunker.
Ronnie and Donnie each had their own heart, stomach, liver, lungs, kidneys, arms, and legs.
But they were joined by their urinary tract and had a semi-shared bladder that emptied into one penis controlled by Donnie.
Thanks to 30 years in the circus, when they retired at 39, the twins could afford a home and had supported their family.
