It was my blood pressure that got me back on bikes. (stop me if you've heard this already) One day at work I asked a nurse to take by blood pressure just for grins. She didn't grin. She turned white and sent me home with instructions not to stroke out on her.
OK, a year and a half later, my BP is closer to normal, and I still have weight issues. BUT my O2 sats are up where they should be (upper 90%s) and my up-and-about (as opposed to resting) heart rate is down in the upper 60-lower 70 range. (I can check these easily at work) There has been progress.
One thing though, the BP meds come with a warning that they make you sun-sensitive. True. I'm learning to ride in long sleeves and use much sunscreen - or ride at night.
Give big space to the festive dog that make sport in the roadway. Avoid entanglement with your wheel spoke.
