I realize you think that, and many do especially those of us who stay in good or great shape due to vocation or choice. I'm a surfer, still do, surfed Maui at the age of 60, plan to do it at 70 and 80 as well, blood pressure at the doc's office yesterday was 128/75, no drugs at all. I could not run a sub 5 forty Im convinced and I was considered fast at one point. The truth is you cannot train fast, God gave it to you or He did not. A 5.0 forty time is fast, chances are the fastest kid you knew in high school, unless he was an actual D! type, on your track team ran a 5.0 or slower, few crack 5.0.
I am convinced some of you have never A. been on the field and watched a sub 5.0 cat play and run circles around everybody else out there or B. have highly inflated opinions of their former selves, the Al Bundy syndrome, you know scored 4 touchdowns in a single game guy.
