Gustavo is chair of medicine and director of the Australian Institute for Musculoskeletal Science at the University of Melbourne.  He is one of the primary people working to further research and awareness regarding a recently recognized condition called osteosarcopenia.  We talk about what osteosarcopenia is, how the muscular and skeletal system interact, what we can do in terms of treatment or prevention, and why it is so important that osteosarcopenia be recognized as a major health concern.
