He had stage 4 cancer according to Itumbi. That can fu.ck you in many ways very quickly and even best medicine can't help. The cancer cells would have entered blood stream and lymphatic system - and can basically decide to go anywhere they want - and cause damage there. You deteriorate very quickly. I saw it with my sister and my dad. My father for once was never ever sick - he was superhuman - and was proud about it - he thought cancer affected other people - not him - but at 76 he quickly deteriorated thanks to aggressive cancer.
Raila looks healthy - not lost weight and all that - but he had something like drainage bag - Anyway, I don't think he is doing very well.Politicians love the media. A day without them appearing in media is bad day - for Raila to disappear for two weeks is tough. These are people who hire their own media to accompany them anywhere. And then we have COVID-19 that is sniffing any weakness.
Anyway, I wish Raila well, I won't wish anybody bad health.
