Meet Jack Lucas, born in 1928.
After sneaking into the Marine Corps three years early, he was determined to see combat in World War II, but military censors busted his plans when they figured out he was underage. First grounded to driving a truck, he then got double-grounded to making small rocks out of large rocks before he snuck onto a transport ship heading out into the Pacific theater.
When he finally was accepted back into combat, he found himself on a little island called Iwo Jima. Yeah, that one. In a trench under fire he saw two grenades land in his trench, whereupon he jumped on top of the first and pulled the second under him, saving his fellow soldiers and gaining some impressive internal shrapnel decorations.
Oh yeah. He survived.
After World War II (and a lot of surgeries to try to patch him up), he did the only logical thing for a man of his temper. He enlisted again. This time, he joined the Army. In his first airborne jump he was the first man on the ground.
The problem? He was also the last man out. Neither his main nor his backup parachute deployed.
He lived with only minor injuries, and two weeks later he was jumping out of planes again.
Even later, one of his wives tried to have him killed. (He survived).
Finally, at the age of 80, Jack found something that was able to fell him in the form of leukemia, but able to rightfully claim the title of the (Mostly) Invincible Man.
