I am so relieved. I am now convinced that Dr. Lung was not feeding me bullshit. I will get back to breathing like I used to and doing what I used to do. I've spent may days since the first of December thinking I never would. That pool had better be ready for me on Saturday!
Earlier today, I gave the scooter a bullet test. I went uphill and down and rode over broken pavement and it did fine. It does need a better horn/bell. But otherwise, it is solid. And now, it may well, be my umbrella scooter that I rarely, if ever use because I no longer need it. Fine by me.
