Medical studies and articles, and prescribing information for drugs, sometimes refer to differential effects in the "elderly".

Is there a standard definition of "elderly" in medical usage? Possibly it's an informal category, just as in normal speech. I'm trying to find out whether it has a precise medical definition.

Note that I'm not looking for guesses. Obviously anyone can guess, and I can guess myself. What I'm looking for instead is whether the word has a precise, generally accepted definition in medicine. If so, I'd like to know what the definition is (what cutoff age or age range).

Thanks.

And what would the consequences be of putting it in an animal that takes longer than the regular human 9 months to develop?

Would the development of the child in question be slowed in order to accommodate the mother's gestational period?

Or would the child come be born developmentally farther along than a normal baby?

And what do you think would happen if this embryo was not only placed in another primate, like ourselves and gorillas, but in some other mammal, like a horse or a cow?


A friend and I got started on this topic and I find it completely immoral, and OUT of the question. As far as creating animals with human DNA in order to create organs to save the lives of those with organ failure, I think it would be alright. But creating a human/animal hybrid would be wrong.

Although, I've seen some half man/ half winged horse photos in Greek mythology that were pretty good looking! ;-)


I'm interested in hearing your answers!!
