I got distracted and now notice that I didn't respond to you, Nuduke, as intended.
Those government guidelines that you present seem kind of self defeating to me. My thinking is this, an idea that jumped out at me while reading "Born to Run."
It goes like this: There's a Tarahumara guy in the Copper Canyon that runs 25 miles to town and back and doesn't think much of it. That's just how he goes to town. He is 85 years old. Why and how can he do this "feat" so easily at that age. The answer is, NOBODY EVER TOLD HIM THAT HE COULDN'T!
Age is very much up in one's head. Such thinking needs some mental exercise to wash it out. Most oldsters just don't believe. or believe that they are old. They can certainly do lots more.
Age can be calculated in many different ways. I may be 26 in one way, but 76 in another. We have to address every aspect, but over all, I'm doing things that will make me around a healthy 42. That's my job, now. I'm retired from the other business and have time to take up this new occupation of gathering new habits. I don't think that I have anything better to do, so it is supposed to be priority.
Being habitually physically lazy, easily distracted and lulled into old habits the new job is a challenge. Getting up to heavy breathing at least once a day, and better still two or three times, is a challenge. I still associate that with discomfort, instead of health and normal exertion. Stationary bike that I sit down on and read to not get bored is there, but getting in the daily habit is another thing. Doing sprints in the yard is curious and I'm having better luck with it. Long term jogging on flat unnatural surfaces gets to my knees and ankles. I don't think that it is healthy over time.
Getting different exercise in, alternating the days is very complex and I lack discipline about that kind of scheduling. Still, I keep up my attempts, keep a tell tale diary of it, at least and someday, I'll meet many of those goals.
So, anyway, we CAN do this, achieve and live much longer and better.Life is a precious gift and it is foolish to squander it, even a day of it, or diminish its potential, or limit expected quality of it by ingrained belief. Government suggestions are based upon statistical studies of people who generally share a common expectation and lifestyle, which includes a ton of self defeating behaviors and thinking.
