Man lives on the 80th floor of a block of flats. In the morning he gets in the lift and presses ground floor and goes to work. When he returns home from work he takes the lift to the 40th floor and walks the rest of the way. Why?

on a farm there are 3 fields, in one field there are 7 stacks of hay, and in the second field there are 8, there are none in the third field, the farmer then combines all the haystacks from the first and second fields into the third field...how many haystacks are there now?
