This photo has been mirrored to show a mans inner struggles. Perhaps it is bipolarity, or some other internal mental health battle.
A man holds his hand on his forehead as he struggles with despair. Perhaps he has an addiction, maybe money issues, perhaps he has a migraine headache, or maybe he just can’t find his keys!
The guy you are looking at is Astronaut Michael E. Fossum, in this shot he is working on Space Shuttle Discovery’s cargo bay.
