that old story of hiked a lot in my 20's (Nth QLD), knee surgery in my 30s. In my 40's i went to a pain management course and after this i started doing basic walks/hikes round the sunshine coast. I never completed challenging hikes as much as i wanted as i preferred to do these type of hikes with someone else, super bad sense of direction, conversation and safety. 
Ive been in Brisbane over a year due to a whole lot of things i havent been able to organise an organic reset and fairly sure my mental health is missing this release. Looking forward to going a group being challenged improved fitness and life discipline
