Challenges that harmss people

Challenges like the Tide pod challenge, the cinnamon challenge, the one where you light yourself on fire and may other challenges like this are dangerous. They can harm you and everyone around you and they are pointless to do. Why harm yourself with something that could kill you and make everyone around you hurt? It is not cool. Harming yourself is not cool. Who does that just to fit in but why do things that can hurt you severely and could die from the reactions and affects and even the injuries. So why do it? It makes people look stupid. Why try to fit in to a place that you don't belong in? Why not be your own person and not let people rub off on you and be like hey do this its cool. No its not cool its stupid and pointless and can kill you if your not careful.
