Siyami,

A quick look at my bookshelves found:

"The life of a red corpuscle in a chicken is thought to be about a month,
but a human red corpuscle keeps working for about four months before it is
destroyed."
	Welty, J.C. (1975). The Life of Birds. (2nd ed.) WB Saunders Co.,
Philadelphia. p 116.

Counter-intuitive, eh? One might expect a nucleated cell to last longer
than a non-nucleated cell.
