Norm sad to see you give it up, but with chronic health issues of my own over the last four years I understand were you are coming from as at times I wonder when I will get better and be able to enjoy my life as freely as I used to be able to. Sometimes I still debate on whether I will continue collecting or not once I complete my current incomplete fleer sets. However, I do know that this hobby has kept me sane over this four year period.
If I do eventually give up collecting, like you i will stick around though as I like helping people out with their collecting questions and checking out people's awesome maildays.
On a final note I hope you sort out your health issues and remember you have friends on here that you can talk to.
