A Ukrainian guy living in the US claims he went from sea level in New York to the top of Mount Everest in just four days—no weeks of acclimatizing like everyone else! He prepped by sleeping in a hypoxic tent at home and used supplemental oxygen, but no fancy gases. The record isn’t verified yet, but if true, this is next-level wild. Imagine telling your boss you’ll be back from Everest by Monday! #Everest #Mountaineering #Adventure #Spirituality
