For me, my objection to hair loss is not that I think it will bother other people, but that it bothers me. Even if women, co-workers, and other important people in my life don't mind it, I still mind it, and that matters more.
That said, even I can't say that circumstances don't matter. There are things more valuable than hair.
For the right amount of money, the right girl, etc., I would gladly agree to become a NW7 by age 30.
