As a cyclist, and professional driver it would simply take up too much of my time.

When working I have outside influences and considerations that preclude me doing it. On my own time I tend to be thick skinned and easy going, but also have a temper when pushed, and I have found trouble because of it. Fortunately up to this point it has worked out in my favor, but I know I need to be more restrained as ones luck is bound to run out in time.
