A few days ago an 82 year climber died in an attempt to reach the summit of Everest. He was hoping to break the record set by a climber by the name of Min Bahadur Sherchan, who scaled Everest at the age of 76 back in 2008.

He had little previous climbing experience too. Seems to me that's pushing it.
