When we're young, we look for outside sources in order to understand ourselves. Whether it be music, or visual entertainment, art can be a way for people to connect with themselves but as we age, and come to understand ourselves better, we rely less on these things for answers. This isn't to say there comes a point where we no longer listen to music but our preferences changes and we don't go to music for the same reasons as we used to when we were younger.
Where do "old people" find answers for themselves?
It depends on the person; Some have stopped looking while others have found some of their answers through various sources such as therapy, meditation, friends... the path to answers are as diverse as the people looking for them.
Part of all answers, however, is to find peace with the question. While there are some things that we can understand and improve about ourselves, others will forever be out of reach and we must come to terms with it in order to find some degree of happiness. "It is what it is" is a phrase that ends up making a lot more sense the older you get.
One thing that we all need to keep in mind is that there's been billions of people on this planet many of which have had the same questions/insecurities as us. The most important thing is to educate ourselves - look for answers from those that have been known to have had the same problem to resolve and see if the solution works for you as well.
In conclusion, I want to move away from the subject a bit...
Being older, I now understand that it's easier for companies to introduce new products to children than it is to adults. It's easier to get a young person to start "vaping" than it is for an older person to do so. It's easier for products to get into the minds of young people that are still seeking their place in the universe than older people that have their lives rooted in habits - habits that, obviously, doesn't include said new product. Some of the things that are part of daily lives today weren't for the previous generation and we're the ones that popularized it. A product can consider itself stable once a generation has adopted it and the following generation has always lived with it. It would be difficult, for example, to remove Coca Cola from store shelves as its been around for decades.
