what is nut lock and what is it use for?
Amateurs fight only 3 rounds. Winner's based on the number of blows. Pros fight longer and judged by their performance(k.o. powerpunch, etc). Biggest difference is the PAY. Pros get millions and amateurs don't.
Air and see UV causing buildings to generate extreme heat. You are right about potential CO2 because somewhere they are burning coal or fuel to generate the electricity to run your air conditioner. People assume a light bulb has zero emissions, it has none at the bulb but there are emissions where the electricity is generated. Air conditioners are associated with ozone depleting refrigerants and countries have agreed to eliminate them. The electricity generated for your electrical to run the air conditioner also has mercury and toxins associated with it. Great questions
Amateur boxing is about safety, i.e., the use of headguards, jerseys, and heavier gloves. Amateur boxing is scored on the point system - every legal effective blow counts one point and knock downs and standing eight counts don't count extra. The goal of an amateur boxer is to outpoint his or her opponent. Amateurs do not get paid for competing, however stipend monies are available for elite boxers at the national and international levels. Young boxers, ages 8 to 12, box 3-1 minutes rounds; 13-14 year olds box 3-1.5 minute rounds; 15-16 year olds and novice (age 17-34, with less than 11 bouts) box 3-2 minute rounds. Open boxers (with 11 or more bouts) compete in 4-2 minute rounds. Amateur referees say only three words: stop, break, box when controlling a bout. Committing a foul (slapping, hitting behind the head, holding, low blow, etc.) will give the offending boxer's opponent 2 points. Amateur and pro boxing are two entirely different sports and can't be compared.
