At least Ryoga pretty well knows the advantages of being a small pig
There's that kind of stuff too, I guess, lol. But what I'm talking about is life extension. Imagine:
The year is 2050. Ranma's as old as dirt. He wears adult diapers and dentures, lives in a nursing home, and needs to be pushed around in a wheelchair. One day, he croaks weakly, "Orderly, would you be so kind as to splash a bucket of cold water on my face?" After the attendant does so, he immediately reverts to a redheaded teenage girl in perfect health, who then leaves the facility and goes to enjoy being a young person in the mid-21st century.
