Your personal fitness is what you make of it. A physically demanding job can be beneficial if you also support it with a nutritious diet and maintain proper health. But if your job is physically active and you eat more than needed, it does not matter how much you are working, because you are still consuming more calories than you are burning.
the worst meal i've ever had would be goat cheese. I cannot explain how bad the taste is, its an inexplicable taste. It kinda tastes like soap and rotten yoghurt and the taste lasts for more than 2 minutes, i hope i never taste it again.
