Advantage
Rather than good, useful, or comfortable, ADVANTAGE is something “preferred”.
If you see an advantage in something, it means you like it, are attracted by it.
You “assume” that it is good, from the way you feel about it. So, advantage is all about feelings. Purely.
And then, the next thing human would do is finding some “publicly acceptable” explanation for something having an advantage.
More than that, human seem to have a lot of fun trying to define and set the standard for what advantage should be.
Human try to hide away their feelings by covering them up with some standard they create just because some “no one” has said feeling is not a valid reason!
