It's time to grow out those 'staches and raise awareness of men's health.
Movember started at the beginning of the month. It encourages men to grow out their facial hair and start important conversations about men's health.
On average, the lifespan of the average Australia man is four years less than a woman. Nine men die from prostate cancer every day, while more than 200,000 are living with the disease.

Meanwhile, suicide is the biggest killer of males under 45-years-old. On average, six men take their own lives every day.
Those taking part in Movember just need to let their moustache grow for the month, while asking their family, friends and colleagues to donate.
Money will go towards prostate cancer and testicular cancer services, as well as mental health charities.
Anyone can sign up for the challenge through movember.com.
