Always was taught that older people, are just as fragile as young ones.
let’s come up with one, two, or three ways in which you would try to make their old age easier on them. 
a) take away fallable objects from their way & walk with them in natural surroundings at their pace
b) converse with them to help them recall their lives’ good memories with them
c) keep it silent and soft/low in noise respectively, when they are around - resting or awake
