why ask why

people keep asking me, "are you going to continue to do ironman races and other races" and"why do you do this to yourself?". All I can say is I am going to do what makes me happy until my money or my health runs out, yeah days get hard , but at the end of more days than not i look back and say i've had a good day and I lay my head on my pillow and sleep like an untroubled child, and wake up the next day and watch the sunrise and smile.
