Twenty-five, I'm pretty sure you mean a CO detector, CO2 is carbon DIoxide which is relatively harmless and a natural part of the breath we exhale. They are part of code in many places but generally only if you have gas burning appliances as far as I know. After hearing this though it makes me think maybe they should be required in all houses with attached garages as well.
My local club used to use the regular night club method of different color wrist bands and X's on hands for under 21 customers and X's for the under 21 dancers too. I definitely understand wanting to avoid the risks and make it 21 and up though.
My local club used to sell beer, was BYOB for liquor, no smoking, and 18 and up. Now it's beer, no more BYOB, smoking, 21 and up. I'm not sure if the change was a club decision or a change in local laws.
