Heh. Would that have net a positive or negative impact on your health?
From the perspective of the genes, having kids but being unhealthy is better than being a healthy loner. And this is good health in a larger, cross-generational, perspective
Could have gone the other way and cost you a family in a DUI accident, or cost someone else's theirs. Hopefully you were wiser than taking such chances, and things worked out well for you (divorces not withstanding).
In the aggregate and with better public transportation and mental healthcare maybe it can be a net win for everyone. Yet I have doubts.
It can vary hourly :)
Bullshit. Sober people go out socializing, their way to socialize is just different, and they have no trouble finding partners. If you had decided to go without a drink, you would have found a partner, just a different one from different social circles.
This wholly depends on where you are in the world.
