33. Stop Tanning.
Going to the tanning booth is one of the absolute worst things you can do for your health (via cancer.org). That luscious tan may help you feel more attractive, but it is damaging your skin in more ways than we can possibly list here. If skin cancer, liver spots, and excessive wrinkles sound like good ideas, then, by all means, keep tanning. However, stop going to the tanning booth if you want to keep your skin looking young and healthy (via National Institute of Aging).
