Thursday, October 10 is World Mental Health Day, which is an international day for global mental health education, awareness and advocacy against social stigma. It was first celebrated in 1992 at the initiative of the World Federation for Mental Health, a global mental health organisation with members and contacts in more than 150 countries. The day provides an opportunity for mental health professionals to discuss and shed light on their work, making mental health a priority worldwide.

Men are more likely to be colour blind than women. The genes responsible for the most common type of colour blindness are found on the X chromosome, the National Eye Institute explains. Even if women have the genes on one of their two X chromosomes, a properly functioning gene on the other one makes up for that loss. If men inherit the gene on their only X chromosome, they’ll become colour blind.

Fancy a last-minute trip to Melbourne to support the Sydney Swans in this weekend’s AFL grand final? It will cost you!

The AFL grand final typically attracts a crowd of 100,000 and millions of viewers on television.
