I started listening to 60s music lately, it clearly elevates my mood. I can imagine people playing it having big broad smiles while doing it. This isn’t the case nowadays. People are now generally more resistant to stimuli, be it the good or the bad. This is a state of acute indifference, leading to alienation from the world, leading to sadness and leading lastly to an ill humanity. What does it take to notice that it’s raining outside? Two-headed cats and dogs, no less!
