Great and insightful post, love it, keep an open mind, you don't have to worry your brain will drop out! It's really hard how especially the ones with more life-experience become increasingly closed to new concepts and ideas, but such is life, you see what you've trained yourself to see. I try to keep it interesting and give myself a challenge to do something new every once in a while. When was the last time you did something for the first time? Cheers!
