How will they be lonely if the majority of people at 40 will also be single? Heck, even high end nursing homes today have serious “singles” scenes. Online dating is growing fastest for people over 50.
With improvements in plastic surgery and healthcare, people will also look younger in the future. I already meet women here in the city who look 20 years younger than I would guess.
For better or worse, technology will eliminate “mandatory” marriage. On the bright side, people will be free to mingle until they find someone they truly can't live without. I think too many people in the past married the wrong person and got stuck because they “had to”.
And the millions pouring accross our borders will do the job that Americans won't do; have children.
that is horrible
