It's just patently absurd. First of all, a person who is 35 expects their body to live until they are 80 but throws in the towel on learning new skills because their brain is broken? And what about the requirement that the president be at least 35...if he/she isn't able to learn new skills? And then, most importantly, where's the data? I don't observe that people in their 30s and 40s have trouble picking up new skills.
