CSW! It is interesting you say you don't want to pursue MMA but you are talking about mixing your martial arts. :) Maybe you mean you don't want to fight in a cage for money?
Note that the gold reflector will shift the colour temperature of everything it hits, so if you're photographing a model wearing white, and that white has to look white in the final picture, you're just going to have to put things back the way they were in post anyway
Gold is a good conductor of heat and electricity and does not tarnish when it is exposed to the air, so it can be used to make electrical connectors and printed circuit boards. Gold is also a good reflector of infrared radiation and can be used to help shield spacecraft and skyscrapers from the sun's heat.
