My point was that you're introducing the nirvana fallacy: rejecting all attempts because they cannot satisfy a perfect outcome.
That it's impossible to perfectly model reality is not news in any scientific field.
In any case, I was talking about grossly observable variables such as "does this person exercise at all?", or "do they smoke?" or "do they drink?". You'd be surprised how many studies don't bother to check simple factors like these.
