It is recommended to buy a proper health insurance cover first and then proceed towards investments. There are many non complicated products that one can choose to invest-in such as monthly income schemes of post office regular interest paying bonds and immediate annuity plans of Life insurance companies. One can also target regular income in the form of rental income for residential or commercial properties. Some may also find source of income (though not guaranteed) through their holdings in equity stocks. However, it is always advisable to have a combination of products in the retirement basket.
