Sun screen lotion before the climb- Kanchenjunga
Sherpas apply sunscreen before setting out on the climb. The Sherpas are the unglorified climbers in the Himalayas. Every successful expedition that returns home to applause conveniently forgets to mention that these Sherpas led their way including fixing ropes for them to the very top. Without them the climb is impossible. Only few great climbers like Reinhold Messner fixed his own ropes on his climbs.
