He might be living for tomorrow, but is he really living for today? As far as I know he's spent millions on his various protocols and so much of his time and energy. I don't know too much about him... but it's hard to imagine it has been money and effort well spent, especially if it is fairly experimental. Has his effort to live forever prevented him from friend's dinners, family occasions, etc?

Alternatively, maybe he's doing it purely for the content creation, to sell a story that literally everyone is interested in? I imagine, he's made something out of all the podcasts, Netflix specials, magazine articles, etc. I think it's important to ask 'how do they benefit from this story?' to get a read on their intentions and if it's all real or not.
