How many insects do you think the average person has killed in their lifetime? ——— I kill like 2 mosquitoes and 3 ants a day, and a year has 365,25 days on average. A person living for 100 years will live 36525 days, so we multiply it by the 5 dead insects daily and that gives us 182625 killed insects. As most people won't live for 100 years, we can multiply that big number by 0.7, which equals to 127837
