I do not think I am much different that the next person.  Anyone that stops to think about it will almost have to admit that they feel better when they are involved in a regular exercise program.   For months I was enrolled in houston fitness classes and during that time I felt great.  I had energy and I was able to think clearly on the job.  Then I told myself that I was do busy to do the fitness class one night.  Soon I was missing more that I was showing up for and then I dropped out.  It took me months to realize what not going to class was costing me.
