You're clearly wrong as it relates to the post you're responding to. This one data point is going to get him to engage in a behavior that's healthier than the one he otherwise would've been engaged in, which is clearly good. Thus, the data point is useful!

Not everything his to be a double blind study showing significant effects to be useful.

> behavior that's healthier

You presume it's healthier.

Suppose that 99.99% of the 80+ year-olds who try this end up breaking their leg, getting a heart attack, etc., and this one data point is from the 0.01% which benefits.

Likely not - but that's why we have double blind studies.

We _know_ it's 'healthier' than drinking and playing video games.

[eesmith]

Yes, because we have far more than one data point.

Nor am I going to take up smoking because a 111 year old smokes them regularly.

Well, from the one data point @eesmith provided, I'm picking up smoking as it must have done SOMETHIN for that guy.
