Viliam2016 is probably relatively young, healthy and living in a country with a fairly high quality of life, meaning that he can expect to live for several decades more at least. But as humans, our measure diminishes fairly slowly at first, but then starts diminishing much faster. For Viliam age 90, Viliam age 95 may seem like he doesn't have that much measure; and for Viliam age 100, Viliam 101 may look like an unlikely freak of nature. But there's only a few months difference there. So at which point do the unlikely future selves start to matter? (The same applies to younger, terminally ill Viliams as well.)
