Author and former professional footballer, Mark O Brien gives a few of his tips for minding your mental health over the Christmas period. Mark is working with Mental Health Ireland to highlight the importance of talking about mental health and the importance of placing as much importance on looking after your mental health as you do your physical health. Mark began his professional footballing career at the age of 16, playing for Derby County. At the age of 17 he had his first open heart surgery and was forced to have another one at the age of 27, which forced him to retire from football. Mark has written a book about his experience called ‘A Game of Two Hearts’.
