Elderly Challenge - Observation 4

I have noticed many public places such as HDB flats and parks have many stairs. This could result in the elderlies tripping over steps and hurting themselves and tiring themselves out quickly when climbing stairs. This could happen especially to the disabled if there are no railings installed. I feel more ramps should be installed, not replacing the stairs but beside them so the risk of accidents happening will be decreased greatly. People on wheelchairs, both elderly and young, will also have much less difficulty moving down or up.
