Hello @mesola, wow I can't stop gazing at the last photo, you are quite fit in your late 30s, it's amazing. I agree with you just like in my entry, people shouldn't be sacred of aging, however they are actually concerned on the challenges (limitations) it brings.
Cardiovascular exercises and yoga really combine to keep anyone bothe the young and the old, in amazing fitness. Another good and readily available exercise is walking.

Thank you for sharing
