No, Nothing should be mandatory. Only advised. I hate stuff being enforced by law we are not kids. Uk every one is treated like babies you can't do this and that and you're never responsible for your actions it's always some one else who's to blame.
Only things which could harm others should be made mandatory you not wearing ears muffs only harms your self not any one else so is your problem.
Sorry, I can only partially agree with you. Yes, there's many instances of society being coddled these days, but it benefits society too. Every time you visit a doctor or your personal life is impacted by an injury, it costs the system money.
How many lives have mandatory seatbelts saved? I'm not ashamed to admit that a seatbelt saved my life and I have the picture to prove it. I've never had a problem wearing one, but many people do, people who wouldn't wear one unless it's mandated.
Whatever the injury, in our modern society, if someone gets hurt, society ends up bearing a large portion of the cost. That fact is inescapable.
