Buzz Aldrin has a Guinness World Record
Aldrin is the oldest person to have traveled to both the North and South Poles, according to Guinness World Records. He visited the North Pole in July 1998 on board the nuclear icebreaker Sovetskiy Soyuz, and at the age of 86 years and 314 days, he made a tourist trip to the South Pole in November 2016. Crediting someone as the "first" to complete any form of achievement would be futile because records are supposed to be broken. However, Guinness World Records occasionally makes an exception for the most admirable, most recognizable, and groundbreaking accomplishments, singling these "firsts" out as indestructible and eternal. Without a doubt, landing on the Moon checks each of those boxes.
Unfortunately, Aldrin had to be medically evacuated from the Scott-Amundsen South Pole Station to Christchurch, New Zealand, after becoming ill with altitude sickness. Aldrin said in a statement that he felt much better when he reached sea level. Incidentally, the explorer has also been far beneath sea level: in 1996, he ventured to the wreck of the Titanic.
