Let's discuss someone that lives a long time above the median lifespan. Maybe 95. Almost all of their former classmates, colleagues, siblings, cousins, partners, and peers are either dead or too sick to travel to the hospital/funeral. They've likely had mobility, energy, or cognitive problems that reduced their involvement in the community over the last 15 years. Many people 20 or 30 years younger that they might have mentored, raised, or inspired will have passed. To someone 40 years younger or more they would have always been 'old' in their mind, and generational gaps would conspire to make them further apart socially.
Someone that dies younger than median will often have more hospital visitors and more funeral attendees by the simple fact that more of the people they knew in life are alive and healthy enough to travel.
He lived in the same town his whole adult life. Everyone his generation was dead but he had made so many friends, business relationships neighbors and acquaintances over the years it didn't matter. Also helps that he had 9 kids which equates to a lot of grand children and great grand children.
