Issuing a challenge is the In thing now.
It was inspired by the ALS Ice Bucket Challenge. ALS is Amyotrophic Lateral Sclerosis, an incurable degenerative disease. Conceived by two Americans afflicted with ALS, the Ice Bucket Challenge asks someone to have a photo or video of him being drenched or he can drench himself with ice water or else donate $100 dollars to an ALS organization. He will then issue a challenge to more people daring to do the same or donate.
Or they can do both. The drenching and the challenge to other people should be posted in social media.
Never mind if many of those who had themselves on video being dumped with ice water on the head just wanted the publicity and didn’t bother to know what ALS is all about. It’s for a good cause anyway.
