It's a sunny winter morning and you're walking along the beach.
A few months ago, after your check-up, your doctor told you: «We need to keep your blood pressure under control. I'm prescribing a medication for you to take every morning, but I also recommend exercising and taking a nice walk every day if you can. Start gradually and try to build up to about ten thousand steps a day, but don't overdo it.»
You are fortunate to live in a coastal city. The beach, especially out of season, is an excellent place to enjoy a free and easy walk and breathe in the fresh air.
