Have fun trying to climb it
Mt. Everest is the largest mountain in the world and it is in the himalaya mountain range. Over 200 people have died trying to climb this mountain. Climbing Mt. Everest is the opposite of cheap, it costs anywhere from 10,000 to 100,000, that's about as much as some houses.
If you do manage to climb the mountain and make it back alive then you will become worldwide famous and even your favorite celebrities will want to meet you.
Wool jacket, long Johns, wool pants, etc. an oxygen tank, a tent, and hiking tools.
Make sure you're in a group so you're not alone so then if you get sick someone else could take care of you.. Have an oxygen tank near you at all time just in case, because there is very little oxygen when your going up the mountain. Keep hydrated, you could get altitude sickness.
If you liked Mt. Everest..
Then you'll love to go to Kangchenjunga and K2 one of the next tallest mountains in the world.
