Think also you can have skin problems like infection or something... So, important is to get clean yourself and also the smell for others is not a nice thing
Yes and no. As far as I know, skin infections can indeed occur if you don't wash yourself enough, especially some parts, and not washing for 5 months is definitely too little and risky (I remember an acquaintance telling us about having to scratch the dead skin of a grandma who didn't shower, because the skin was cuting her blood flow), but washing too often also damage your microbiome and can have the same effect.
If showering once a day is probably not "too often", it's not necessary either though, at least if you don't have physical exercise or weather that recquires you too.
why he dosen’t get dirty as us if he lives in the countryside? He is literally a teenager and during puberty,we all know that it’s very easy to smell bad. Also,there are some parts of your body that you should wash everyday for your health and love for yourself. Also,don’t forget that he works in a farm.
BEcause the air pollution in a city is worse than in the middle of nowhere. I literally turn grey in city at the end of the day.
However, you are right about the teenager part but, unfortunately, that's the moment of the ife where a boy is the less liekly to take a shower...
I also mentionned that physical activity = shower.
