no, he hasnt.. but he planned to do it this friday... gosh... im so worried bout him... and he doesnt listen to me... now he is having trials and he still want to do this challenge..
i asked him to dont do it but he said its just for fun
i dont know how to advice him anymore

Did he do it yet?
If not, reason with him why this ice bucket challenge is bad for his health and why this challenge is a bad way to promote ALS attention(? Not sure if this is the right word).
