In researching their bios common characteristics include the following:
1. Proper nutrition and diet
2. Active lifestyle and exercise
In the case of Johanna her ability to maintain he level of gymnastic skill is is based upon a important principle that I believe to be true;
"If you don't move it, you lose it".
If you perform a task/functional activity consistently (at lease 1 time/week) throughout your life, you will never loose the ability to do it.
One functional activity that older people lose is the ability to get up off of the floor from a position of supine and feel that it should be practiced at least 3 times a week by anyone over 50. Ideally one would alternate the leading leg when getting up. I like this skill as it involves many mini tasks that contribute to a person being able walk, balance and maintain independence.
These tasks include:
1. Dorsiflexion of the ankle
2. Hip Extension
3. Quad/hamstring strength and control
4. Rolling/Abdominal Core activiation
5. Toe extension
I believe that if every person over the age of 50 did this one simple task every day, falling and consequences of falls would be diminished greatly.
Becoming a member of the "Elite Elderly" is not easy but with some practice indeed possible. When one considers the alternative, it is definitely worth the effort.
