Obviously, there are obvious things that fails you such as drug tests and what not if you were to score a positive. But I guess people are saying that you can't legally do drug tests unless you notify the candidate.
Anyway, I am not wondering about how the airline medical goes with respect to drug abuse, just general life style? such as weight limitations? cholestrole? HDL/LDL? Hemoglobin ? Hypertension and all that kind of stuff. Like I heard a guy who was refused an airline ground school class due to Low Liver Enzymes.
What I guess appeals to me the most would be the lifestyle corresponding to weight, body mass index, height, and the other concepts? what's acceptable? Because I hear many people tell me about how for example people who are overweight fail the medicals, yet I see a bunch of pilots out there who do look rather overweight.
Yea... just wanting to get an insight from all you airline guys

Thanks so much !
