ALL of this is done by human hands. You need to have experience in the work, show dexterity, patience, and then the result will really be obvious. Bravo to the Masters of their craft.I take this moment to give thanks & respect to the hard working people of the world who make the world what it is.Some build & produce by their back & their sweat. The real heroes of the world.Deep respect for every hard worker in the world. I wish people would be more aware of the hard physical work other humans have put into stuff. Bless your strong and tired bodies and souls after (too) long hours of working.
