The 'Life Clock'

Nothing seems unusual when you first look at this clock, however, upon close inspection, you will notice that the numbers seem a little high. This is because one full rotation of this clock is equal to the average human lifespan (82 years).

The clock, designed by Bertrand Planes, uses an ordinary clock slowed down 61,320 times to make each minute equal to one year.

Some people would find this concept quite depressing. I wouldn't recommend giving it as a gift to a childless, single 30-something woman who is already well aware that her biological clock is ticking, and that the years are slipping away.
