You are a mathematical genius who was instrumental in breaking the codes used by your government's enemy to help win the second world war. Your brilliance helped pave the way of the modern theory of computation. How does your government repay you for your loyalty and service?
By chemically castrating you.
You can't get it up no more, humiliated by the witch hunt trial that ended your career by taking away the security clearance required to do your job and kill yourself at the age of 41.
Fifty five years later, the Government apologised. Gee, thanks, Mr Brown.
