They say experience is the best teacher. Sukhmander Kaur Sanghera is 88 years old, and has learnt much in her eventful life during which she has experienced a closed economy as well as today’s globalisation. Her most important advice? “Save money for your retirement and old age,” she says. “Spend money only where it is necessary. Don’t waste it,” says the octogenarian, who is an avid card player. Planning for retirement is easier for those who get pension; “those who don't, need to ensure they save money that will accrue interest,” she adds. Being prepared for emergencies is also important so keep some liquid cash, she says.
