The reasn he did nt use medical equipment such as a micrscpe was because they did nt exist during his time. Further, understanding f germs and bacteria was still develping, and he had t innvate methds himself based n the thery he believed
2. Hw has Jhn Snw’s wrk affected ur daily lives? Snw's wrk has prvided readily available clean water t drink, fr example, as well as an emphasis n hlygiene such as the need t wash hands after they becme dirty.
