Received a reply from my email to Brian Cox earlier.
Apparently, it's now a confirmed scientific fact that tree's have become more magnetic over the past 50 years due to modern day air pollution. Tree's can now cause very small electro magnetic changes in air density due to small changes in the gravitational pull of the earths natural magnetic field around them.
Today i made some very minor adjustments to my aim when shooting very close to tree's and i scored hits on every shot !
So is it ,as some may think , B***ocks ?
