If you had a choice would you rather go deep sea snokeling or go skydiving?

How can you snorkel in the deep sea? Don't you have to have the end of your snorkel above the water in order to breathe? Do you mean SCUBA diving? If so, I choose skydiving due to my insane fear of being deep, deep underwater. Snorkeling is fine with me, though, and I find it quite enjoyable.
