Which proves my earlier point.
At your age you think you are super human. As a blacksmith you will become very strong but PLEASE take care of yourself. We have winches, hoists, pallet trucks, forklifts etc. for picking up heavy stuff. If you strain your back it might never recover so please use correct lifting equipment or get someone to help you. Also heed the warnings of those with more experience. Wear steel toes, safety glasses and all the other modern devices to protect yourself. This includes hearing protection. I am nearly deaf largely due to my own stupidity and it is no fun.
