Ceiling vs. Floor

Why would anyone in their right mind put a heater vent into a ceiling? It makes no sense at all - and I will tell you exactly why.
1) How can you sit on it to keep warm if it's in the ceiling?
2) How can you use it to dry your clothes that didn't dry on the line overnight when you're running late in the morning?
3) How can you put your underwear on it to warm up on a cold morning?
4) I could be wrong here, but I think basic science tells us that hot air rises - so you're denying the warm air the right to fulfil it's scientific purpose if it's already at the top of the room
5) How can you find that last 50 cents to pay the pizza guy on Friday night when the number one storage area for lost poo-change is upside down and hanging from the ceiling?

Craziness, I tell you.
