    The original post only gave half the explanation. It’s not that lead exists in general, it’s that lead exists within zircon crystals.

    Under normal circumstances that would be impossible, zircon crystals strongly reject lead atoms as they form. There’s no way to stuff lead into the crystal lattice in the quantity we find them there. But uranium and zircon go together just fine, we just have to wait for it to decay into lead. The trouble is it takes ~4.5 billion years for just half of those uranium atoms to turn into lead. So any zircon crystal we find with half as much lead as uranium must be roughly that old




















  • 80k is the federal legal weight limit for a truck and trailer, and that’s spread across 5 axles. and any single axle can’t be over 20k. an f650 is big by pickup standards but midsize at best by commercial truck standards. look at any pictures of f650’s in use and the biggest loads they pull are single-axle beer trailers. no trucking company is pulling their 53’ tandem axle trailers with f650’s

    almost any trailer approaching weight limits is going to be attached to a fifth-wheel, which puts load on the truck frame by design. literally the reason we call them semi-trailers. you’ll never see anything with a pickup bed hitting 80k gvw

    sure, you can upgrade the entire drivetrain and suspension and reinforce the frame to get an f650 to handle nearly double it’s rated capacity, but at that point you’re just putting an f650 cab on a truck fit for the job. OPs pic is an f650 with an f350 bed slapped on it and a few other cosmetics
