Here is the image of an important activist and humanitarian. I am reminded how he is not in good health but choose to engage in reminding how important he is and how his presence has helped society in many ways.
I am sorry to hear he is in poor health due to age and a recent stroke and now lives in Brazil full time. I have found a few articles and podcasts that reflect on his health and points of view on many subjects.
I tried to find the most recent public image from google.

It is interesting to discover these recent developments and think many people may want to be aware as I do. I certainly wish him a speedy recovery and pleasant stay in Brazil.
