This should work, but due to a problem with Scratch's timers, it doesn't. You can look inside to see my scripts. They make sense logically, but they don't work. Gen A dies at age 62 and Gen B starts living a year before they are born. I was hesitant to copy down any information from this because it might be wrong. I stopped partway through because I realized that my numbers would be drastically different from the real ones.
