Prof David de Kretser, outgoing Governor of Victoria has warned Victorian parents that their children risk living shorter lives than their grandparents because they are too fat. Governor de Kretser, a former Father of the Year, Monash Institute of Health head and eminent medical researcher, said childhood obesity and climate change were the biggest challenges facing Australians and predicted future generations of Victorians would be crippled by health problems unless children lead healthier lives.
