Twelve-thousand people in Ireland have Parkinson's disease, a degenerative neurological condition.
Today marks the beginning of Parkinson's Awareness Week, which will focus on what it is like living with Parkinson's.
Dublin man Tony Brady has been teaching his grandchildren about the condition he lives with.
His philosophy remains, live life to the full.
