What are the physical characteristics of a healthy person?

I'm referring to Joshua Engel's answer above. He describes the physical characteristics of a healthy person quite well. But is this sufficient? I've worked and lived with beautiful young and older people who'd shown the exact features described by Joshua. Living with them meant for me, getting up in the night and washing them, when they'd shit in their pants. Getting them to eat their meal several times a day. Not letting them walk alone out of the building. And so on. Those were people we would consider as ill. Mentally ill. Their only problem: their IQ was below 60, often not even measurable. In the stone age some of them would have probably survived by using their animalistic instincts. Today they live protected from a world, which doesn't tolerate "normal" animalistic behaviour. (Our world tolerates psychopaths, on the other hand...) That said, these men and women were all friendly loveable charming personalities. So physical characteristics might not refer to features we would like to see in a person.

well I would think first off a healthy weight
