If that had any relevance to our inherent circadian rhythm, it would be shorter than 24 hours, not longer. pjk > ("Are we not men?")

If the basket contained a (large) unknown negative number of apples this method could be quite expensive. I propose to weigh the basket, then tip the negative apples out of the basket and weigh it again. Calculate the difference and divide it by an average weight of an apple. This method works reasonably well unless the basket also contains some negative watermelons. pjk
