Hard to get the proper shots if the FDA doesn't even know what the proper shots should be... Flu mutates rapidly, that's why we get updated flu vaccines every year.
That's what they think too. Unfortunately, they are yet unable to buy immortality. You cannot buy something that does not exist. They cannot pay money to buy knowledge from thin air, or manufacture a product with no lead time, no matter how much money they have.
They can however seclude themselves on a private island and live vicariously through a phone screen in a reality of their own. Until wifi drops, at least.
"the event" is exciting. fresh and new. a real challenge. Afterwards... is boring. sucky. nobody wants to be there. so don't imagine it. they could head to their bunkers right now, if they wanted. but they won't. they just keep waiting for "the end" that never comes. The game doesn't stop, the credits don't roll.
A billion dollars won't buy you the exit from the rat race. Try again.
Yeah but at their age there is still a good chance they get wiped out if they get hospitalized by the flu and they are unvaccinated even with good healthcare. And if they survive good chance the flu will advance their dementia to the next stage.
