No worries it's a long way down exploring the world all the way down to the size of the planck length. Sure we won't understand the tiny dimensions in our lifetimes, but, in fact we have already lived long enough to witness breakthroughs to tiny dimensions. We use sub micron gadgets every day, including embedded in the computer I'm typing my message into this very moment.

There is so much convenience all around us it makes one ask, 'do we really need to go anywhere?' Well yeah, in a month or so I have to wander out in the yard, clean it up and get some seeds and plant sets going. My back gets a twinge just thinking about that. :-)
