I find it true, the enthusiasm and enjoy that we used to have while younger was much more than present. It may sound non technical discussion but I am curious to know Is there is any scientific reason for same ?
I don't have a scientific explanation, but personally, I think this has to do with a change in circumstances as we age. During my younger years, I used to go to festivals, enjoying the moment, drinking and having fun, not necessarily worrying about the day after. Nowadays, if we can arrange a babysitter, you know that once you get back home, there will be kids that wake up early irregardless of your sleep deprivation and/or hangover. That prospect makes enjoying the actual event more difficult than say 20 years ago..
So now we go to kids festivals instead, enjoying the fact that they are enjoying themselves!
Could be a certenly " Life Low", but I have not determinist. We can change of aptitud now, and today!!...This is a free and firm decission on each instant.
Try to add some science :) Mostly likely, the very pleasure remains the same. But I think with age we begin to compare this joy with the negative effects associated with festivals and parties (like noise, crouds of people, alcohol, midnight taxi, late go to bed etc.). Surely it is, I'm about 60 and have some understanding. So the recipe is as follows: you must ban yourself thinking about this bloody negatives. Finally, this extra shot or two won't immediately kill you.
