How we could improbe on this is by {for}
Housing- All flats and houses should have lifts for the physically disabled , Braille for important signs like DANGER!! or DEAD END AHEAD etc. for the visually impaired and very important for all elderly all houses' lobbies must have parapets in case someone falls and worse case dies.
Accessibility to places - Like some ,unfortunately not all, buses should have the slope door so it is easier for the old to get in the bus.
Caring - We could give up pur seats when we do not need it and when/if a elderly is having problem doing something like finding the toilet or crossing the road we should spend a few minutes helping them.
Opportunities - Sometimes old people have a lot left in them but they do not get the opportunity to show it. Thus, we should also invite them and play around with them like go on outing or do a elderly track and field or something. I will also now spend time with my grandparents.
