Congratulations on reaching the milestone of 70! Age is just a number, and it's wonderful to hear that you still feel young at heart. Taking care of our bodies becomes increasingly important as we age, and I admire your motivation to get fit and prepare for your upcoming trip to the Netherlands. Regular walks can indeed be a great way to stay active and improve overall fitness.

It's unfortunate that walking in your suburbs is no longer safe, but it's fantastic that you have found a solution within your own property. Your garden workout sounds invigorating, with the flight of steps, steep driveway, and the level lawn with shrubs. It's always fascinating to discover how plants have grown and transformed over time, creating a beautiful environment to enjoy.
