BobbyW - if I am down that way ill pop in
Gav- i have just read and catch up on your post and sorry to hear you are giving up biking, i was in the same position, i gave biking up for 2 years before coming back.
The winter and cold air affect me the most, I see you have type 2 diabetes and diagnosed with COPD same as me, only just yesterday I been for an electrocardiogram (ECG) checking my heart again and 2 blood tests, they still trying to find the route of a few of my problems :
:.
As the doctors class me as unfit to work I am classed as disabled, you would think it's fun, but it's Very very Very boring!
So i am hoping once its warmer ill be flying about on my X9 to get my spirits up and feel beeter mentaly mainly being the aim.
I hope it may be possible like me once your sorted ( takes time ) you mite just get on a bike again.
