When I was living and working in Tampa, I worked in a Cancer Center for 5 years. That place literally changed my life, no joke. The amount of research I worked with and diseases I saw ppl go through was tough though.
I remember I had to consent a young guy, like he was 23-25 in 2014 or 2015 to a banking study. Dude had colon cancer and had a colostomy bag. He was doing ok I guess, but seeing that was rough given his age (I was similar in age at that time). Fucking colon cancer is very very rough stuff.
The fact that Chadwick endured all that and still gave us one of the most recognizable heroes in film is still astonishing. Rest in power man.
