Now 68 had some fairly serious health issues about 4 years ago , but have recovered nicely. I am very active but at a bit slower pace. Still scuba, snow ski cross country and alpine, hike about a mile a day and bicycle about 18 miles 3 days a week here at 8000 ft.
I can tell I definitely do not have the strength or endurance I used to, and my lower back, rt. shoulder and knees periodically remind I am not 35.
But mentally the linked test said I am 33 so I guess I must think and act immature
