Welcome to

Random 2: You are as strong as your biggest weakness.

If the above is true. Then your smartest brain cell is only as smart as the dumbest one. Then alcohol must be good in killing unwanted stupid brain cells, as evolution means the slowest member will get killed first while the faster ones get ahead in life. (from a forward today, lol)

All random.

But according to claims. Do you know that we only use 10% of our brains? The 90% is just sitting there like a bum doing nothing. The brain also accounts for approx. less than 2% of our body weight, while consuming 20% of the body's energy.
