what will you choose? swim the deepest sea or climb the highest mountain?

I want to climb the highest mountain so from there you could see everything below. I'm afraid to swim because usually I get this cramps I might drown.

I would prefer to climb the mountain rather than swimming. I love to travel highest places. Though both are full of adventure and provide us new knowledge, but climbing a new hight has another satisfaction. Risk is there in both. In going down into the water, we may be attacked by sea animals etc. We may drown down in deep water. May fall short of Oxygen. In climbing there is also rick of dropping down to surface, short of oxygen. Good health condition is required for both. But my last choice will be climbing a new hight.

I would choose climb the highest mountain cause it symbolizes that I can do anything if I put my mind to it. Plus I know the view would be awesome on top of the mountain

I don't know which I'll choose cos I can't swim and I've got fear of heights. :(
