Those climbing a mountain this winter who do so without wearing the right clothing face another problem in addition to the obvious threat to life and limb - Jeremy Clarkson's tongue.
Fresh from talk of shooting strikers, the TV presenter has said he backs the privatisation of mountain rescue services currently carried out by the RAF, as he does not want his taxes to pay for them.
In his blog, Clarkson said: "Why should I fund the rescue of a rambler? He or she chose to go out there in the mountains. He or she knew the risks."
While the point may be deliberately provocative, those who wear crampons
in winter, warm jackets and the right boots will reduce the risk that they might need rescuing.
Many of those who do need help are ill-equipped for short days and cold weather, such as a trip of eastern European students criticised this week by Lochaber Mountain Rescue for setting off up Ben Nevis without a torch or appropriate clothing at 13:00 BST - just three hours before sunset.
