This is probably one for some of us who have been around But anyone can jump in! I have had a wonderful time collecting . Studying  learning sharing helping. Making friends. But I'm in my late 60's. I still enjoy it. I enjoy the back and forth between collectors. I never got into my coin is better than yours.But get we are proud of what we collect.. My hands are very bad. I'm forgetting allot more. But this hobby keeps calling me back. Sure I have slowed down. But it seems I can't stop. It's like a passion I have. I love to collect. I did stop for two months. But I saw a coin and back I came. So when do we call it over? I don't know.! Do you?

I don't know if this is helpful. I had a golf buddy much older than me. He played until he was 82. One day he hit the cart three times with his club and fell one time. That was his last game. Sure do miss him! 
I guess you keep at it until it holds no interest anymore or you just cant do it cause it hurts more than you enjoy it.

I second Bama!  Push through till you can't anymore, or the pain outweighs the joy!

Yep, as they already said. Continue until you loose an interest, or are unable to continue at all. There was a point where I looked back on what all I had done, and considered just selling it all and moving on. I almost did it, but I made it through. And now, here I am

I had the same experience as CS a few years back... sure glad I didn't!!

I know how you feel, my pain is always there, some days I can't concentrate from an old Traumatic Brain Injury, on those days, I struggle to read blogs and don't even think about looking at coins.  Then I have good days, to use the old movie phrase, "don't give up, never surrender", keep going as long as you feel a shred of happiness or satisfaction out of it.  Nuff said!  Carry on my ANA brother!

I have been collecting since 1979 and have lost interest and gained it back three different times....selling my entire collection each time. I say that we are never done. Once the collecting bug has bitten us I believe its always there. My health has also become worse with my thyroid problems...I have a very bad memory and my concentration and comprehension is not there sometimes but I try to keep going.  I still read as much as I can about coins but anymore I forget what I've read almost instantly. Anyway....once we become collectors we're always collectors....for life. 

Just a thought, is there someone younger in the picture? Say a grandson/daughter? If so, pass it on. That way they collect and you still enjoy.

My thought is that a hobby is something you do when you want and when you don't want to, for whatever reason, you pull back.  The reasons you may have to pull back could include health issues, family obligations, travel for work, financial reversals, or any other number of reasons.  But I don't know that you have to irrevocably pull the pin.As a friend use to say "there are no right or wrong answers.  there are choices and consequences.Good Luck.
