The important thing is that we stay interested and involved.  Sure, there's joy in discovery but re-discovery ain't bad either.  It proves we can still have a synapse (takes at least TWO brain cells 

 ).  I feel certain that MUSIC makes us better human beings.  I feel a little sad for people that don't have it in their lives.  BTW, I (we) love your 'always cheerful' outlook on things.

Hi Chas, so true about staying involved. Hubby has his online video games, communicates with friends from all over the world , 
me, I’ve got my keyboards, might not be much of a musician, but I enjoy it anyway. 
Definitely agree  that music makes us better human beings. 
Oh thank you,   I do my best to try and stay cheerful, who wants to listen to a grouch . Haha.😀
