In 1998, Icelandic electrician Guðmundur Felix Grétarsson lost both arms following a devastating accident involving an 11,000-volt power line.

For 23 years, he lived without arms, unable to hug his daughters or perform everyday tasks independently. In January 2021, surgeons in Lyon, France, performed a groundbreaking operation, giving Felix the world's first double arm transplant involving the shoulders.

Following months of rehabilitation, Felix gradually regained movement and achieved something he had waited more than two decades for: hugging his daughters and grandchildren again.

He has since regained the ability to perform everyday activities, including brushing his teeth, dressing himself, and holding a glass.

To date the clams, it’s necessary to freeze them, split them in half, then count their growth rings.
