You know you are getting old, when the most exciting thing happening is an invitation to test your balance at a Senor's Expo (Thursday 26 May 2022, at Exhibition Park in Canberra). Canberra is having its Seniors Day, with 200 booths. As it happens, I was lunching with Roger Hausmann today at Badger & Co (Australian National University), who mentioned the Balance Mat, will be on display at the expo. The idea is you stand on the mat, sensors measure the pressure changes from your feet, and a computer provides an analysis of your balance. Dr Maryam Ghahramani, from University of Canberra is researching the use of the data for diagnosis.
