Memorialized Accounts

Despite being an important part of English literature and history, very few people will ever make the effort to read it. Most people's Facebook posts don't rise to that level and assuming a generation every 25 years, that's 40 generations and that means that I would be one of ~2^40 ansestors (certainly fewer since there were necessarily be cross linkages in the hundreds of billions of ancestorial chains)...so the odds of a person identifying with me in particular are pretty low.

On the other hand, there probably is a business that involves taking people's money for something that they won't be around to see not live up to its advertising pitch.
