Marylou Tousignant:
He scaled California’s Mount Whitney, the highest peak in the United States outside Alaska, when he was 7; Mount Kilimanjaro, the highest in Africa, when he was 8; Mount Aconcagua, the highest in South America, when he was 9; and Russia’s Mount Elbrus, usually considered the highest in Europe, when he was 11. (Along the way, he received donations and sponsors to help pay for the trips.)
Lets not forget it's big mountain climbing season. Mountains over 8,000 meters are far from most peoples reach. You have never seen mountains this big.
