Not true.
Honest to God, on my way to Miami from Nashville heading to our mission trip in Haiti, there was a Gentleman ( I will call him gentleman because he was very polite) was sitting next to me on teh plane. I noticed he had no hair, no eyebrows and didnt notice any hair on his forearms nor his legs ( he had shorts on). I kept thinking I was going to say something, but didnt know exactly what to say. I was feeling sorry for him because of the Chemo, but he looked awesome with a shaved head. Finally, I think only because he noticed I wanted to say something he just looked at me and said, Go head, ask. I said Excuse me. He said it was OK, go ahead and ask. So I asked him if he had won the battle? He said that he wasnt in a swimming contest. I kinda figured that because he wasnt built like a swimmer. I said No I mean the cancer, did you win? He said no no my friend I dont or didnt have cancer. People assume that I have underwent chemo and its not the case. What he said next ended the conversation. He said, I do it because I like it and because I can.
That is where I Got my "BECAUSE I CAN" motto from.
So not always is it a case of Chemo therapy....it could be just a fetish that person likes.
