Live happier and age better, says a new study published in the Canadian Medical Association Journal. The UK study claims that people who enjoy life and have a positive outlook walk faster and have better physical function than their more negative counterparts.

The study found that enjoying life won't just make you age better, but it'll also help you live longer.

"This is not because the happier people are in better health, or younger, or richer, or have more healthy lifestyles at the outset, since even when we take these factors into account, the relationship persists," explains lead study author Dr. Stephen Steptoe. "Our previous work has shown that older people with greater enjoyment of life are more likely to survive over the next 8 years; what this study shows is that they also keep up better physical function."

In essence, it doesn't matter when you start your mood makeover, it just matters that you do it! So snap out of your bad mood, and appreciate what you have -- it'll help you stick around longer. [Medical News Today]
