Physiological breakdown how? I think you nailed it when you said average. Mean, median, mode, variability, etc. all matter. The fact that the cancer rate is X doesn't imply I'll get cancer. Does the AMA have studies on airline pilots or the general population? So we're dealing with similar but not exact sample populations (with age being the only correlate)? Speaking of, what's the statistical power of those studies. If I'm on your Ph.D committee you're going to have to do a lot more convincing.
"Proof." A very, very strong and confident statement.
