I agree that it must be a fake. I've never experienced anything like this so it can't be real. It is very colourful and sharp and he is a caucasian which is the real give away. It's Vietnam! No Europeans have ever been there! Not to mention the pixels. Someone has spent a lot of time and energy faking this. Who cares why? I can now continue my life secure in the knowledge that things I am incapable of imagining can't exist. Phew!
That would certainly be an achievement but it rather pales into insignificance when compared with the marathon monks of Mount Hiei who start off running a marathon every day for a year and then ramp it up from there for seven years! They run on mountain paths in straw sandals, just to spice it up. Utterly astounding!
