Developing your body takes dedication and sacrifice and with some high level athletes genius like Michael Jordan. You can inspire with your skill, you can teach, You can do heroic things like charge machine gun nest. Sadly time takes your body. An idea or an invention and its benefit can be copied and practiced bought and sold as a commodity for the benefit of the many without knowing the identity of the inventor. Its benefit is long lasting.
Most inventors know that the only glory is the jolt of the idea itself.
The rest is thousands of hours in front of drawing tables, milling machines, lathes, plasma cutters, lousy air and arcs and sparks. I am honestly sure that the public doesn't care about these statistics yours or mine since it is commonly known, that life is often described as quiet desperation. Jack la Lane and I look like a marshmallow. If I take off my shirt you will faint. If you want to be John Henry against the steam engine or pocket calculator be my guest.
