Live to a hundred - The federal government has launched a new website aimed at helping Australians make choices to live longer and healthier.

All residents aged over 45 can take a free online life-check which the government says is a bid to get more people living over the age of 100.

It's a tool designed to help Australians live longer. And while that sounds, perhaps, a little far-fetched, it's possible the online tool could be life-changing.

 Aged Care Minister Ken Wyatt describes Life Checks website as a "reality check" for  Australians aged 45 and over.  He says it will help them make good decisions about health, finances, work, social and emotional well-being.
