An old school friend has sent me pictures of his successful ascent of the Eiger last week - or what he modestly describes as "a long 14-hour day".
So if he can do it ... No, you're right, I'd probably die in the attempt.
Government warning: do not do this without months of training and professional supervision. Climbing one of Europe's most fearsome mountains could seriously damage your health.
