92-year-old George Etzweiler, of State College, Pa., is a runner. He began running at age 49 and has kept it up ever since.

"When I started running, I just enjoyed it," said George. "And especially getting out into the woods. I like to be outdoors and I think most people feel better outdoors. It just seems psychologically better for some reason."

"Exercise seems to be showing up as one of the very important facets of healthy living," said George. "Feel better, sleep better, better health."

Members of the "Men of the Mountains" running team, including George, right, run on the Tussey Mountain trail in Boalsburg, Pa. on Feb. 27, 2012. George founded the team in 2007 to run the Tussey 50 mile relay race. "The rules are, you have to be over 65 to be on the team," said George.

"Usually I'm running with somebody and It's just a friendly occasion," said George. "I do a lot of talking, gasping sometimes to talk, depending on who I'm with and how hard they're pushing me."

George points at a table showing the running statistics of members of the "Old Men of the Mountains" running team in his State College, Pa. home on March 15, 2012. "I'm team captain, organizer, timekeeper and record keeper," said George. "I decide who runs each leg and also estimate how long it will take for them to run each leg depending upon the terrain."

George is always training for the Mt. Washington road race held annually in New Hampshire. The race is 7.6 miles in length and has an average grade of 12 percent with a 22 percent "wall to the finish" for the last 50 yards. The course rises 4,650 vertical feet from start to finish. Just the vertical climb of Mt. Washington is over 1,000 feet greater than the tallest peak in all of Pennsylvania. Here, members of the "Men of the Mountains" running team train on the Tussey Mountain trail, a five mile round trip run at a nine percent slope, in Boalsburg, Pa. on Feb. 27, 2012.

"I'm a celebrity up there," said George, as he looks at a copy of the Centre Daily Times featuring an article on his running of the Mt. Washington road race in New Hampshire. In 2005, George took 30 minutes off the previous record for the over-85 division and has been invited back to run ever since.

"I'm classed as an elite runner just because I've lived long enough to get to the top of that mountain," said George regarding the Mt. Washington road race. "People say 'You're my inspiration,' and all I can do is shrug my shoulders. I don't know what I did."

George's wife, Mary, was a great inspiration to him. Mary died in December 2010 of pulmonary fibrosis, but her passing did not stop George from running the Mt. Washington race in 2011.

"Most people my age are dead," said George. "But, it doesn't worry me at all that I'm not going to live forever - I don't think it ever did worry me. People ask me 'How long are you going to keep this up?' and my answer is 'As long as I can.'"
