obviously not enough

Dear Brain,

Yes, playing softball twice a week is better than nothing, much better than nothing, actually (and hopefully it will be twice a week, though for the moment it looks like it might only be once a week, dammit), but it is obviously not enough. Do you hear me brain? I am slowly dying at a gradually increase rate with each lazy year and if you do not send signals to the legs to run more and to the other muscles to exercise more, I will be dead (and that just might be the end of you, for all we know). Besides, I will perform much better (and you will be much happier, especially your ego) if you get me in better shape.

Sincerely,
Your Body
