Baird was 54 at the 2006 Olympics on U.S. curling team. He was an alternate on Pete Fenson's U.S. team, so he never actually threw a stone but still shared in the bronze medal.
Affectionately known as "Grandma Luge," the U.S. Virgin Islands native has competed in six Winter Olympics, the last one in 2006 at age 53. She was born April 12, 1953. She's currently training for the 2016 Summer Olympics as an archer.
Savage was 52 years and 267 days old when he competed in figure skating at 1932 Olympics. He won his first medal at the U.S. nationals when he was 49 and qualified with Gertrude Meredith at age 50 for 1932 Olympics. He also won the first-ever ice dancing national title in 1936 with partner Marjorie Parker Smith. He continued competing -- and winning -- at the national level until age 63.
The oldest Nordic combined Olympian from any country, having competed at 39 years, 115 days in the 1928 Olympics. He also holds the distinction for being the oldest man to ever receive a Winter Olympics medal (for ski jumping). He was 86 when he got the bronze medal, but he was actually technically 35 when he won it at the 1924 Olympics. A scoring error discovered in 1974 handed him the medal. He also competed in the 1928 Games at the age of 39.
