The importance of mobility is demonstrated by the enormous leap the quality of life of older people took over the last 20 years. This improvement is predominantly attributed to a denser public transport, cheaper cars, scootmobiles, rollators, improved electric wheelchairs, taxis-to-share and the like.
Our quality of life is defined by our mobility. That sounds a bit odd from someone who spent a substantial part of his life in traffic jams and overcrowded trains. But there is another side of the coin. Another type of mobility that is even more important.
Adequate mobility is critical to a satisfactory old age. Although, satisfactory is not by definition healthy. Our mobility also depends on our physical condition. And a good physical condition is the result of an active life. If you want to stay mobile, stay active. If you want to stay active, stay mobile.
