Plastics in our body

Only fairly recently we have become aware of the dangers of plastics in our environment.
For a long time we thought these plastics would not be of any concern to us. However, invariably, most plastics end up somewhere in the environment: they sit at the bottom of the sea, mix into beach sand, and blow in the wind. They’re also inside us.

It's possible that humans may be consuming anywhere from 39 to 52 thousand microplastic particles a year. With added estimates of how much microplastic might be inhaled, that number is more than 74 thousand.
People who drink only bottled water ingest an additional 90 thousand particles.

When researchers from Johns Hopkins looked at the impact of eating seafood contaminated with microplastics, they too found the accumulated plastic could damage the immune system and upset a gut's balance.

Scientists are scrambling to understand the dose at which microplastics start to have noticeable health effects. Like air pollution or harmful construction materials, those who have more exposure or pre-existing conditions may be less able to tolerate plastic.

How did menstruation become a taboo word?

Why don’t we call menstruation by its name but use expressions like 'auntie Flo comes for a visit'? Euphemisms serve a purpose. They give us words to talk about things that are considered culturally taboo.

Menstruation stigma is a form of misogyny. Negative taboos condition us to understand menstrual function as something to be hidden, something shameful. And by not naming a thing, we reinforce the idea that the thing should not be named.

But have periods always needed code words. Where did these words come from, and how did they come about? Were periods always considered a negative experience?

Menstrual euphemisms and taboos are old. But not all societies view menstruation negatively.
Menstrual taboos are found in the holy books like the Quran or the Bible"

“…in her menstrual impurity; she is unclean… whoever touches…shall be unclean and shall wash his clothes and bathe in water and be unclean until evening” Leviticus 15

Taboos on menstruation may have existed before agriculture started or even before languages fully evolved.
