fresh ideas, old body.

Let me tell you this.

As you age, your brain gets better while your body weakens. Yes, the genius gifted talented minds of science "peak" in your 30's.

But dim minds like mine that start out with so little and learn slow, continue improving until death. Some of the greatest artists are like the dim like me. They never stop improving (them because they are so gifted, and me because I started dim and learn slow)
