point to a slim guy and state that the two of you are topologically equivalent! one can be obtained from the other by stretching or shrinking, and you both contain the same number of holes!

It would be a better joke without the explanation at the end, IMO.

I just gotta say I really like your attitude.

What if the slim guy has more piercings than you?

Then your reduced surface area makes you more heat efficient!

You mean surface area to volume ratio. And the insulation probably doesn't hurt either :)

it also makes it hard for you to be digested, by say,

a raptor?

(not really, they would chew you up. only holds true if you stay whole, like say, by a T-Rex. I just said raptor for shock value.)

Two spaces cannot be homeomorphic if one has a larger cardinality. A fatter person has more fat cells than a skinnier one, and so the two cannot homeomorphic.

Assume an ideal fat person.

Assume an ideal fat person.

Then we can optimize the math by treating him as a single point (assumes American (spherical) shape). BLACK HOLE!

No because his digestive tract goes all the way through, so he's more like a donut. It's not topologically the same as a sphere.

You might not be so fat if you'd just stop eating all those coffee mugs.

Depends on how you define person. If you define a human as the subset of R3 that they occupy (perhaps with some property associated with each point), then the two sets have the same cardinality, [imath]2^{\aleph_0}[/imath] (and presumably, the same topology). Your definition is somewhat more spurious though, since representing cells as isolated points is even weirder. Also, as it happens, you're factually wrong. Fat people don't have more fat cells than thin people, they have bigger fat cells.

I think that the sinus cavity provides some additional holes.

I would agree that a person has genus at least 3.

i'm pretty sure its possible to have both more fat cells and bigger fat cells. iirc putting on weight when you are young tends to increase the number of fat cells while when you are old tends to increase the size of each cell but i don't think it is a strict rule.
