my bmi is 19.8. that period looks weird. where is it really? does it really exist?! oh god. oh man. 19.8 is my bmi. oh no. 8!? i am severely underweight. some countries use commas 19,8. looks better, i guess. but then americans use it to split thousands. so that gets confusing. too bad chinese people split numbers into tenthousands instead of thousands. it gets so confusing.
