As if freediving wasn't challenging enough, watch this guy do it in the Lotus position.
Stig Pryds occupies an interesting position in the realm of freediving. For most people, descending to 70m, 80m or 90m underwater is life-threatening.
For Pryds, it's the only way he can live. The Dane suffered from psoriatic arthritis for much of his life, but he's found that the best way to reduce his pain isn't medical drugs but pressure – the kind that only comes when you're deep underwater.
