prof raju is a very interesting person. i met him and started discussing human hair.
prof raju told that there are about 150000 airs on an average mans head. i disagreed with him.
i told him that no one could have actually come by this figure - who would have patience to actually take a man's head and take the hair and count them!

'no' he argued ' it is enough to count them on one square centimeter of a man's head and knowing this and the size of the hair covered surface , one can easily calculate the total number of hairs on a man's head'

then he popped a question at me.it has also been calculated that a man sheds about 3000 hairs a month. can you tell me the average longevity of each hair on a man's head?

can you guess what the answer is??
