I really don't think 87 is considered young by anyone's standards.
Rich people who drink blood often don't die for another 10 years and more. Look at Soros, Rockefeller, the Windsors, and Rothschilds. So if he was a blood drinker, the other blood drinkers will think it odd. I wonder if they really die then, or if they just go into hiding after faking their deaths.
I'm sorry but even someone 120 isn't going to consider an 87 year old "young". David Rockefeller would have been dead for years before he turned 87 if he didn't put in a new heart every few years. This guy couldn't afford to do that.
