When I was younger, everything felt more vibrant. Now it feels like things are a bit duller or less intense, even though life is objectively better in many ways.
Is this just nostalgia messing with my memory or is there any actual psychological or biological reason behind it?
Does anyone else felt this too?

So how long does it take and how can I earn them. And where do I check them.

Please guide me. Thank you.
