I’d need specific examples to really tell you. I’m not stupid but I’m not insanely intelligent either but I value the little bit of knowledge I have so I would have a hard time giving up even the small advantage I have over the more average people.
On the other hand, I would really enjoy being physically attractive seeing as how I’m nowhere near what you would consider to be ideal, either in my face or overall appearance. Hell, I’d just settle for average.
