Why Do We Get Slower Reactions?

People have come up with reasons why it might be that we're slower. My favourite guy who studied this was am the 90 third most cited psychologist of the twentieth century. He is called edwin boringan. I s e must be people slagging him off indirectly by just putting a little asteraski t the bottom, saying, boring ha, ha, haha.
