I don't have rare circumstances or skills that makes these gains difficult to replicate by the vast majority of able-bodied adults. However, your current circumstances and lifestyle will likely need to be proactively redesigned to maximise the benefits of switching to cycling and prioritising your quality of life. Most residents of Melbourne (or similar cities) could also cycle for at least some of their trips and start redesigning their lives and taking advantage of these benefits. If you own a car, the biggest gains are realised when you eventually get rid of it and come to depend on cycling and walking as your primary means of local transport.
