CLIMBING -- Alex Honnold, 31, has been raising the bar to seemingly unreachable heights for rock climbers since he was a teenager. This weekend, we realized that we overlooked the possibility that he's simply not human.  That's the only way mere mortals can sort out how he has developed the skill and nerves to defy gravity and do the seemingly impossible by solo-climbing Yosemite's El Capitan without the aid of a rope.

In 2015, a pair of climbers made the first free ascent of El Cap without using aid, but they still used ropes during the 15-day climb to catch them if they fell.

Honnold went top-to-bottom rope-free in 3 hours 56 minutes. After the first two minutes, virtually any mistake was certain death.

National Geographic magazine termed the feat as "The Most Dangerous Rope-Free Ascent Ever."

Holy crap.  Where does the bar go from here?
