Not a surprise that using the creative side of your brain aids in brain health.

I walk a lot.  I read and think about what i read. 

I dont feel old except for my body a bit...

My main interest before my retirement and after was a challenge : building a relatively satisfying system/room at no cost...

I had done it mainly exploring acoustics  applied and theoretical...

Now my challenge is understanding A.I. and using it for my ideas in mathematics.

I listen music now no more frustrated by "bad sound" ... Then i come backhere because of the people, i cannot say i am in the same  excitation for products, or any audiophile project, my goal was reached...

I walk my 2 dogs too .... One is Boris, we saved him after mistreatment and he is devoted to my wife in an astounding way... We adopted Rita a Cuban female dog  from Havana very typical  race there ...

 We do not picked or choose Rita when we take her, there was many dogs proposed for adoption, we let Boris make the choice... A good idea, they are in love and eat on the same plate and slept glued to one another ....

I use headphone and small speakers and i started a thread recently  about Schumann generators  even if i feel less engaged in the hobby , because i implemented them as i did in my first room and the effect is the same ... The cost is peanuts... And the generators gave something nothing else can gave ... An acoustic cherry to the acoustic cake...

No chit Sherlock!

It’s important to have a purpose and to keep moving in retirement.  I did a lot of research and preparation so I was mentally, emotionally and financially ready.  I’m more into this hobby than ever along with more time for family, boating, cars, homes and travel.  I highly recommend it and hope everyone has the opportunity to experience the joy of not having the stress and time drain of working.  I loved my career and enjoyed a lot of success.  I’m using that same mindset to successfully enjoy retirement. 

@bassbuyer , I see you're a Patriots fan.

You live in New England?

@ghdprentice   I could not agree more.  I have many other hobbies beyond audio and the love of music.  After I finish listening to my morning music and coffee, I will head out on a 34 mile bike ride (on a FWD recumbent I built up from a frameset this past winter).  

While all my different interests could occupy my time nicely, I was not brave enough to fully retire.  I continue to work part time, when and where I want, hopefully serving others in a positive way.  It gives me satisfaction that my often solitary hobbies can't.
