<s>[INST] Is a thumb war violent? [/INST] While it is possible that a thumb is pinned down roughly or a hand grasped too tightly the game itself is not violent in the way a real war is.</s>\ <s>[INST] Could I hurt myself? [/INST] It's highly unlikely to hurt yourself playing in a thumb war, assuming you don't have conditions that negatively affect your bones.
The most damage you can receive is probably a cut from opponents nail, if they are not properly trimmed.</s>
