when singles get old with no one to take care of them den they need to think of ways to make things more convenient for them.
example, stay near a clinic/ hospital, dun stay in high floors.
renovate the house or get a house that is designed to be friendly to elderlies (like heavy things in the bottom drawer so if drop injury won't be so serious). In short, elderly proof your house.
have enough emergency funds.
have access to ask neighbour for help or make more friends in the neighbourhood in case immobile and need help to go hospital.
before reaching silver years, invest in your health so later years won't have ailments, ensure got insurance, anything can contact insurance agent. these are quite basic.
make enough medical preparations.
engage lawyer to do your will.
future proof your silver years, the only person you can 100% rely on is yourself. if you dunno what to do, chances are your children and grandchildren wouldn't know too especially when they haven't reach that age. relying on children/grandchildren is a fallacy.
