This person is 72 years old. Maybe people don't understand what parents mean by "kids take a lot of work". Take everything you do right now and double it. Maybe triple it, because it's harder when they don't know what they're doing at all and you need to teach as you go. All your household chores: double. Work: double (homework). Getting friggin' dressed in the morning: double. Wake up extra early too because school starts at 7:30 and they can't eat their own breakfast in a timely fashion, let alone make it.

That's not to mention that at 72 years old, there's a good chance he's going to keel over and leave that child fatherless pretty soon. Super traumatically too because guess who's going to find his body after he passed in his sleep?
