New Delhi, June 10 -- Are some dreams worth sacrificing? For a growing tribe of double-income, no-kids (Dink) couples, the answer is a clear "yes". These are dual-income households that have chosen not to have children, by choice or circumstance, and are, as a result, rewriting the rulebook on what retirement can look like.

The Dink lifestyle is often associated with freedom-freedom from parental responsibilities, from stress, and sleepless nights. But beyond these preferences, there's a financial case, especially when you crunch the numbers.

A Mint story earlier estimated that a parent spends roughly Rs.25-50 lakh on a child's school education, depending on the type of school they select. Higher education costs are even higher.

Radhik...
