Sorry, I remember reading about it but have forgotten why. All I remember is that it has to do with ears being cartilage and it is caused by a regenerative malfunction (well, that's my excuse)
wow! you so know im straight round the local old folks home in the mornin to check this phenomonen out! ..........just had a thought tho.....maybe ears dont grow but your face shrinks.....or somethin....maybe.
