If you startd saving for your pension at the tender age there's every possibility is that you will have a huge amount of money to use in the future for a very good business.Personally I think no agebis a specific age but all age are good age to start planning for your pension. Anyone who plan early against the future, will reap early and better.
Actually savings for pension at a younger age is the best option which will helped you save more than enough before you could get old, it has begin to multiply in bring much income.
