We evolved living in smaller cooperative groups, and spending most of our time in nature. The farther we move away from that the more we might want to question whether any individual change is actually going to make our life better. Likely some tradeoffs are absolutely worth it and some probably not.
A reason should be given, for what seems altogether inconceivable, how this new relation can be a deduction from others, which are entirely different from it. But as authors do not commonly use this precaution, I shall presume to recommend it to the readers.
It's about balance.
Not really? Historical life expectancies were low because it was so common to die in infancy and childhood (thus dragging down the "average").
For people who made it to 20, it was common to live past 60.
I'm guessing they are ignorant of historical facts and are just repeating what they heard from somebody else.
That doesn’t sound any better.
It doesn't, because "it was so common to", as OP stated, is not the same thing as "you were supposed to". There's no reason it should be corrected, it's accurate.
