Further to the above, probably to live a healthy life-style for the elderlys, walking around the playground is only a basic need.
Singapore's population is ageing. What was really necessary was an exercise / physiotherapy centre with the basic equipments for hand, leg, body and mind exercise.
Each morning besides elderlys who are doing some walking exercises, there are many on wheel-chairs cared for only by maids. What the maid lacks, besides pushing them around, are further education on feeding / meals and medication. Techniques in wheel chair transfers and the many aspects of caring for the old.
These facilities should be on the ground floor, run by health-care-assistants, a physiotherapist headed by a certified staff nurse. In this case, fragile residents, senior citizens and maids can gather for sharing knowledge, learn to care, simple nursing training, medical advice on how to care and look after the elderly etc.
This is something new ( unlike Day-Care Centres and Nursing Homes ) a project worth talking to the authorities, if there is a demand.
