Probably not. Great cause, but kids would make something sexual out of it. Kids that age don't think about breast cancer. I wouldn't want my kid, especially a girl, drawing attention to bewbies in that setting or that context.
There's been a lot of people who've inspired me during my life. But the one who really changed me was a beautiful blue-eyed little girl that was born just over 21 years ago. Holding my daughter in my arms made me realize that I had to be the kind of man that every kid needs as a father. I've looked at a lot of things very differently since then, and the rewards have been well worth the change.
