Do we have enough for our retirement?

This is the question that I keep asking myself. Each time I look at my parents mistake, I keep wondering if we will go down the same path as them. My only consolation is that, with CPF Life, you get your payouts month by month, so that you can spend each month base on each payout. The older folks who retired many years back didn't have an annuity. When they withdrew their CPF by the lump sum, they suddenly found themselves extra richer and started spending more without thinking of the future. Medical costs are inevitable. I've not heard of an old person without any health problems. We'll need money for medical costs and daily expenses. Plus there will be inflation. Keeping the lump sum in a bank account will cause the value to depreciate due to inflation. These are just my own thoughts. So many things to think about in the future and everyone needs money and it's worse if a person is retired and has no more income. Sigh....something more to reflect upon as each day goes by.
