You probably think it's mankind, Gazza. But Terry Pratchett would not agree (read Pyramids, the sphinx part )

Out of the back of my head, it came down to something like this:

If we divide the day in four parts of six hours, three of which represent a life, night not being used, and the average life is, say, 60, the four legged one should only be able to walk on two legs at the age of twenty. And aged fourty, he'd already need a walking stick.If we make it 90 to make the latter fit better, you couldn't walk until you were thirty, and need a stick at 60.
So the formulation is not entirely correct. The child should only crawl until it reached the age of 2, so that's 2 years out of ninety, which equals x hours out of 18. The x equals o.4 hours, which is less than thirty minutes.
Most people also don't need a walking stick at 60 already, ut maybe eighty would be reasonable. Some maths show that the twolegged period would be about 2 hours longer than the 12 from the original riddle.

So, for the question to be at least a bit more correct, it would be

What creature walks on all four legs for almost half an hour during the morning, on two legs for the rest of the day until two hours into the evening, and on three legs after that, roughly?

In which case, the answer Man would be more correct


Oh, and the other spy riddle? I knew the answer once, but I forgot [img]graemlins/heee.gif[/img] But from the way you've formulated the question, the spy outside the wall can see all the others. Then again, he can't tell the answer without any of the spies talking as that would require him to speak [img]tongue.gif[/img]
I'll be thinking on it.
