Why Greenland?
"The Greenland shark is the world’s longest-living vertebrate (400 years +). [...] Researchers have long thought that the Greenland shark lost its eyesight over the course of evolution due to its lengthy lifespan and dim environment up to 10,000 feet deep in the ocean. [...] But now, scientists say these sharks seem to maintain surprisingly sharp eyesight over their centuries-long lives."

The Dear Leaders of Russia and China were recently discussing how to live until 150 by swapping their old organs for young ones. But 400, take that Vlad and Xi!
