Acclimatize in bed, reach summit in half the time

KATHMANDU, Nepal - As other Qomolangma hopefuls were trudging up to base camp in April, Singapore-based Brooks Entwistle was at home, planning his daughter's 13th birthday party and preparing for his company's annual general meeting.

But at night he would climb into a hypoxic, or low oxygen, tent meant to mimic the thin air at high altitude.

Now on Qomolangma (known in the West as Mount Everest), Entwistle, a partner with Singapore's Everstone Group, is hoping to summit the world's highest peak in just 35 days - half the time of a conventional climb.
