7. Good point about the speed, the rest is only relevant if you want to be a hero and the problem is usually solved by the person being in a group of heroes.
6. uh.... every single comic book has taken that into account, well maybe not Hulk... ;D The solution is they hold back. The second scenario as just stupid.
5. If your body adapted a way to run that fast, one your speed will still be limited, two your body will be adapted to withstand the heat generated by friction and of your body. Being to run so fast you create fire like it suggests you would also be burning an incredible amount of calories and eating no less than an elephant a day will be able to sustain you. Since there's no way to shove an elephant down a humans mouth, you would probably wither away to nothing within a few days.
4. makes a few good points, like, people don't think in complete sentences and you would be over whelmed. Yet, it completely ignores the fact that if your brain evolved to where it could pick up brain signals from another brain (oh yeah, you'll be able to read your cat's thoughts too by the way) it would have picked up an adaptation to prevent you being over loaded in any way. Oh and since you are picking up brain signals from other people, you can expect to never lose a fight again (if your reflexes are as fast or faster than the other person) because you will be getting the signal of any move they make as soon as it is sent as well.
edit: The question is: our thoughts in words or pictures... I probably would be pissed if I had to listen to "meow meow" all the time... LMAO
3. That's true
2. any problems with touch, taste, and smell could be an issue, but since vision will still be very important to you as a person... you get the picture. Hearing, you get some freaking ear muffs! You don't need a damn water tank like in Dare Devil.
1. Immortality.... Oh yeah, I feel so horrible for God... if there is one!
