You are right, Boateng,
It's not rocket science to maintain a healthy lifestyle.
A little commitment will help to keep us in shape.
It's also important to tailor your exercise routine to capability and age.
If cycling is no longer good for you, just walk, but do it consistently.
Above all, it is best to incorporate "moving our bodies" into our daily activities by every means possible.
In no time it becomes a lifestyle.
