Thanks for your thoughtful comment.

I'm still doubtful about Bryan's understanding of entropy. His declared aim is to regress his biological age to the state of an 18-year-old.

But either way, we will see what happens.

You are absolutely right about the benefit of trying to halt aging using currently available means until we have better solutions. It is kind of reaching the escape velocity from aging: keep up healthy life long enough with whatever means are available so that you survive to benefit from the next generation anti-aging interventions
