A Recent study showed the impact of certain bad habits by estimating how many days those habits shave off your life. It showed that smoking a pack of 20 cigarettes a day cuts ten years off your life. Cocaine addicts lose up to 34 years, with each dose costing 5.6 hours. Methadone users cut their lives by 38 years, and die at an average age of 41. A heroin addiction will cut 42 years off a person’s life, killing them at age 38. Lifetime methamphetamine users lose 42 years, each dose costing 11 hours.
Murder could be worse: If a 70-year old is murdered, this cuts about 10 years off his life, but if a 10-year-old is murdered, this cuts some 70 years off his life.
The only thing worse that I can think of is abortion, which cuts 80 years of your someone else’s life.
