I have a ton of respect for mountain climbers because of the skill it takes to climb, especially without any safety equipment. Just a sack of powder and your hands. I don't even climb down tall stairs without a safety line, and I always keep a sack of powder with me anyway in case I want to disappear like a ninja. I don't, however, respect mountain climber's life choices. Why you'd bet your life against your grip strength. That's a bet I'd lose in the first five feet.
This picture at Cala Sa Nau Rocks in Spain is trippy. You're not quite sure if the climber is upside down or if the camera is upside down. Either way that looks like an incredibly tough climb. He'd have to have super glue hands just to stay up there like that.
