How foolish of me, in retrospect, to have expected I might learn something interesting from this documentary. For its 90 minute run time, the actual salient facts of Bryan Johnson's longevity project come few and fast. He exercises an hour a day with three intensity sets a week. He's vegan. He takes a hundred or more "pills." Beyond this, the story focuses on his relationship with his son, a little about his past, and makes passing attempts to frame the controversy surrounding him (there isn't much) and to enter the conversation on public health.
I'd hoped to learn a bit more about what he's actually doing, what vitamins or pills he might be taking, but with only a couple of exceptions, this and many other facets of Johnson's project remained unknown. I realized that this is likely because those aspects are proprietary. This is Johnson's personal quest, but also his enterprise. So the "debate" over whether he is altruistic or some grifter seems answered by the nature of the documentary about him itself; to really know about the man who wants to live forever, just plug in your credit card number.
