What are the advantages of being weightless?

Weightless? Like... in outer space? Or just not weighing very much?

Well, lower gravity makes you taller, and can even help improve your posture. I'm sure there's more, but I just don't know 'em.

Would also mean much less muscle. You'd also be restricted to the food supplements provided as growing or making your own would pose as a challenge. Don't know how healthy (or tasty, for that matter) that is for you.

It also cause bone loss and can induce organ atrophy which is why astronauts have to do so much exercise.

It will make it much easier to reach those high up shelves... (Honestly, I dunno, I would not really consider being weightless to my advantage.)

Eternally perky breasts?

Well... at least until death.

Traveling at a faster velocity around the earth in a weightless environment means you live longer because time travels slower.

Its actually harder to keep your body working in zero g.
