SEALY, Texas -- If you have ever thought 'I'm too old for that,' well Jack Grayson will likely change your mind.

Grayson was born on October 8, 1923. On Tuesday, to celebrate turning 90, he jumped out of a plane.

Grayson, a former Nixon administration official, said he’s not one to back down from a challenge.

Grayson jumped from a plane at 14,000 feet and soared through the air at more than 120 miles per hour.

Grayson attributes his good health and energy level to many years of exercise, a good attitude and a good wife.

“But your attitude is one of the greatest things that will keep you alive,” he says. “Never think of the end, always think of what you’re doing.”
