Geezer breeders don't give a fuck about the kids they make, plain and simple. They get to flaunt it to the whole wide world that their fertility is still in full swing and they might not even have to go through the entire 20-year sentence because odds are they'll croak before their kids become adults. Plus they have a little home-grown caregiver for when they do become too infirm to care for themselves that can't refuse or leave. Because you KNOW damn well these assholes will groom their children to believe that they absolutely must care for them and that there is no other option.
And why would you want to subject your child to the pain of their parents' death when they're still so young? I know parental death can occur at any age, but I'd say if your parents are eligible for Social Security when you're in grade school, there's a far higher chance of them kicking the bucket when their child is still very young.
Normally nature imposes an age limit on breeding, but I notice a lot of geezer breeders tend to be older men with much younger women because what 60-year-old woman is still fertile naturally? Why the fuck are men fertile for that many years anyway? Is it to make up for their inability to have multiple orgasms or something? Nothing wrong with relationships that are a bit more May-December, but you know men who want to prove their dicks still work intentionally seek out women who can still get pregnant - who cares about the heightened risk of birth defects, right? Because I wonder who will wipe Mommy and Daddy's asses when their child turns out to be a tard.
There is no feasible reason why someone nearing retirement age should be making more kids and this is a perfect example of why. The mom's death was unexpected, but if it weren't for the healthy older sister, these kids would likely have all wound up in the system and never gotten adopted because nobody wants a child more than two days old. That responsibility should not fall on the sister, but it has because these two morons had to breed.
