I honestly think we should live more for the now than the far future. Rather than focusing on how to optimally extend my lifespan I'd rather focus on living the life where I'd be satisfied if I dropped dead the next day.

Like the article says this is only one of the many causes you could possibly work to prevent and if you die of something else then all that effort was for naught. Whereas if you put all your effort into living a worthwhile life then it doesn't matter what you die of or when.

I understand this man has kids he wants to live long for and that makes optimizing for living a long life worthwhile to him. But I don't think that a long life should be the goal in and of itself, it should be to live a worthwhile life.
