Tony Cetera is 79 years of age and has bad legs, but that doesn¡¯t stop him helping the homeless whenever he can.

His philosophy and process are simple and unstructured, but if everyone followed his example, there¡¯s no denying it would make a difference.

¡°Just try to do good,¡± he says. ¡°Even if you just give one can of oil sardines to the guy on the train who hasn¡¯t bathed for a week, your mission for the day is done.¡±
