Power curve hacks from traveling abroad

So in Spring of this year I spent 20 days in Europe. When I got back to the USA, my body was totally different for 2 months. I completely mistook this for "having found good spots in the USA", but actually it was a delayed reaction to the Power Curve benefits gained from being OUTSIDE the USA. I am astonished at this realization and that it took me so many months to put the pieces of the puzzle together. But I'm here to tell the story now after having just left the USA again, twice, in the last month.
