Like all skiers, our pulses quicken when the snow begins to fall, but you can have too much of a good thing. Dont believe me? Try skiing in near-blizzard conditions, when you can’t read the surface of the piste you’re negotiating, thick mists have blotted out even long-familiar features and the wind is strengthening by the minute. When you get assailed by all three, then it’’s time to do the unthinkable and head back down the mountain to sit out the storm.
