David Attenborough has much more to achieve - namely finding the Abominable Snowman.
Although the naturalist isn't “necessarily” sure he believes in its existence, hunting down the Yeti is still on his to-do list.
“I mean I wouldn't mind finding the Abominable Snowman for a start,” he said.
“There is still a mystery about the Abominable Snowman. There are teeth that were found back in the 1920s, huge molar teeth about six times the size of ours, immense things, they were found in a Chinese druggists store and undoubtedly are the teeth of a giant ape that must have lived relatively recently itself and that could have been the Abominable Snowman.”
The Yeti or Abominable Snowman is rumoured to live in the Himalayan region of Nepal and Tibet. Stories of the creature first emerged in the 19th Century, but scientists have written of the mammal as a myth in the absence of sufficient evidence.
However, Attenborough says the mystery surrounding the Yeti is exactly what draws him to finding the creature.
“I don't say I necessarily believe in it, I'm saying that there is evidence and of course one of the very difficult things ever to do is prove a negative, to prove that it doesn't exist,” he said at the launch of UKTV’s new season of programmes.
The broadcaster has had a number of animals named after him including the goblin spider (Prethopalpus attenboroughi), a fossilised fish (Materpiscis attenboroughi) and a fossil grasshopper (Materpiscis attenboroughi).
