Yeah but they aren't your bits are they
I've bought and paid for this belly, raised on the finest Guinness and pies, so I am pretty sure it belongs to me.
If you don't own your own body who does ?
Donk, I have a printer that I am giving to a friend because I no longer have use for it. I am happy that someone else will make use of something that for me no longer has any utility or much worth. Chances are if the friend remembers/gets round to it he'll slip me a bottle of wine or two. I would be rather unhappy with friends popping round with a stack of post-it notes with their names written on them, slapping the post-its on random items and announcing "that's mine when you've breathed your last".
