21. Washing your hands removes or kills germs (soap breaks up oils and viruses; water rinses them away), which prevents you from spreading or getting infections.

22. Antibodies bind specifically to germs, neutralizing them and marking them so immune cells can destroy or remove them.

23. HIV attacks and destroys CD4 (helper) immune cells, weakening the immune system so the body cannot fight off infections and illnesses (leading to AIDS).

24. Preservatives slow or stop microbial growth by removing water (salt, sugar), changing acidity (vinegar), or otherwise creating conditions that prevent rotting.

25. Everyday actions: eat a balanced diet, get enough sleep, exercise, wash hands regularly, stay up to date on vaccines, manage stress, and avoid smoking.
