Sorry I accidentally pressed reply without adding anything.
To respond to the machine elves question, I dont know much about them but from what I read, they arent similar to the stereotypical grey (and also while a lot of people describe similar things, they do differ in appearance from time to time)>well they're sure better off than you or me
You do have a point, they are on average taller, wealthier and healthier but those three originates from their ancestry (who also are the reason for their large wealth), although maybe devil magic comes to play because it's a wonder how they havent became homeless from all the dumb shit they waste their money on
Finally >They'd just be heroin addicts if this were true.
There's a reason the wealthy elite were stereotyped as crack addicts from time to time during the 80's, I think they got bored of that too, your brain increases the threshold for serotonin release when it keeps getting released (likely from their rich foods and crack).
