Replying to People You Respect the Most

For me:
-Olympic Marathon runners (Just something about running 26 miles in a little over 2 hours is absurd and not many people in this world have the skill or desire to do it.)
-Anyone who has climbed Mount Everest (I think only around 1000 people have successfully done it and its a pretty badass task to accomplish. Supposedly some guy para glided down it which is fucking sick: http://www.usairnet.com/2011/05/paragliding-off-everest/

I could probably think of a lot more but thats what I came up with off the top of my head.
 
Your turn, Go!
