The thing between my ears, it has never let me down.
But aside from that, I suppose I like my eyes for how well I can see, and my hands for how well I can make things thanks to my eyes being so good.
I have the unthrilling waist, but, my lifetime of always walking, while not always joyously expressed through my usually sore feet, has at least made it so my body is generally fat free (aside from the tire at the waist). My limbs are not what you routinely got on an overweight person. Aside from the waist, I don't really look like I am as heavy as the scale says. Who knows, muscle is heavier that fat. And I have large upper legs. There's a lot of muscle on them.
