You may be able to measure deterioration in the brain between 20 and 30, although I am skeptical. I would love to see some supporting links if you have them. What does "somewhat" mean? 1%? However, there are many other advantages that come with years of experience and learning that I suggest would outweigh such deterioration. Startup success may perhaps correlate inversely with age increase from 20 to 30 (although I doubt it), but I would be surprised if "brain deterioration" was the cause. I often compare programmers. I haven't seen the evidence you see.
