I can ask a random person on a forum asking about arbitrary levels of "realness" to solidify what they mean.

Maybe I wasn't clear. I'm not asking for metrics that prove, without a doubt that something works. That is clearly what scientists should be doing, not, as we agree, a random person on the internet.

I'm asking for what metrics OP would accept as evidence that would convince them something works. That is something that scientists would not have a say in.

Would peer reviewed papers qualify? Would a random blogpost? Where is their bar set for things that would actually change their mind?

I'm actually not sure where the line is drawn for "life extension", and would appreciate your two cents. Does a healthy diet, regular exercise, and ample sleep fall under that in your experience? Why or why not?

I know this guy does a lot of super off the wall techy stuff, but the foundation of what he focuses on seems to be pursuing these things (diet, sleep, exercise) with militaristic discipline.
