Shaquille O’Neal “Shaq” stands 7 ft 1 in (2.16 m) tall and weighs about 325 pounds (147 kg). If I was an explorer and saw him...I would say he was a giant of a man.
Robert Wadlow - He reached 8’ 11.1” (272 cm) in height and 490 pounds (222.26 kg) in weight. Thats big!
Bao Xishun, born in Inner Mongolia, measured at 2.36 meters (7 ft 8.95 in) tall
Leonid Stadnyk is said to be 2.54 m (8 ft 4 in) and weigh 200 kg
And then there is the poor kid Brenden Adams - was 7’ 4” at age 12. He was 4 1/2 feet tall as a 5 year old! http://slanchreport.wordpress.com/2009/11/05/75-middle-schooler-is-a-big-target-on-the-football-field/
So could there have been a bunch of people whose had a genetic tendancy for active pitutary glands or whatever and be called giants! Yes, no doubt about it.
Brendan Adams is only 14, and he’s already 7 foot 5 inches — making him the world’s tallest teen, according to Guinness World Records. He’s always towered over his classmates, and now he’s finally gotten medical clearance to join them on the football field. Brendan, who lives near Seattle, has a body full of tumors, had his spleen removed, teeth problems, bad arthritis, and a heart arrhythmia, so it’s been a struggle to get there.
