Well Muscledrifter, using your logic, I guess you don’t have windows in your house? Because if you wanetd to, you could just step outside to see the sun . Sun roof, a window on top. yes a window, you have them in your house and at your work, but i guess if you live in a cave you dont understand. Heck even my tent has a screened in roof, and I can ot be any closer to being outside then that.
