I don't know where you get your information about me supposedly being a troll. That comment is total bullshit, and if you read much substance of my multiple posts, you would realize that I make my posts with genuine attempts to communicate relevant ideas and without any ill-intentions towards anyone, except maybe trolls.. hehehe, which I again assert that I am NOT... . Accordingly, I even stated in my earlier post (and I meant it) that I did NOT make my comments towards Rpietila lightly or with any maligned intentions towards RPietila.
Regarding the substance of your comment. Lighting and angle are NOT going to account for the bad health that is depicted in such picture. Genetics may account for some of such depiction, and I stated that I was sorry, if genetics were the case... and that is why I largely attempted to focus my comments on the three main controllables (diet, sleep and exercise).
You realize you post in a forum where, by virtue of the topic and the alignments with that topic, there's probably a pretty big overlap between users here and the crowd that populates your typical computer science/physics/math department...
When was the last time you have been to one of those? I'm afraid, you'd be advising
a lot of people on the "three main controllables" in one of those
