Oxygen

26,000 feet is the so-called "death zone," above which there is not enough oxygen to support human life. Oxygen tanks would probably be advisable for anything over 20,000 ft, or perhaps less.

   The altitude that you would need oxygen tanks would be about 18,000 feet.

   If you are climbing slowly (adjusting your body with the oxygen deficiency) and if you are a healthy person, up to 7000 m you would not feel much difficulty. Even beyond that you can pull on till you reach the top of the world, but keep a cylinder ready. But remember, from 5000 m onwards, your body will start getting tired easily and hence your climbing will be slow.

   That depends on your age and physical condition. Could be anywhere above 100 feet if you are 110 and smoke 6 packs a day.

   Typically, above 17,000 feet, the oxygen content of the atmosphere is lower than what the human body needs to be effective. With training, you can lower your oxygen requirements to be able to sustain activity at higher elevations.
   Only a few people have the ability to go without oxygen for short periods above 26,000′ (see Reinhold Messner).

   Most people that climb Denali (Mt Mckinley, 20,320′) do so without oxygen, but there are also many cases of altitude sickness every season on the mountain because of it.
