Can a grain of sand kill you?

“An amount as small as a grain of sand can kill you,” Dr Karen Grimsrud, Alberta’s chief medical officer, told reporters after traces of carfentanil were found in the bodies of two men who had overdosed. “Carfentanil is about 100 times more toxic than fentanyl and about 10,000 times more toxic than morphine.”

Why do they say fresh as a daisy?

In Old English, daisies were referred to as “day’s eye” because at night the petals close over the yellow center and during the day they re-open. The phrase “as fresh as a daisy” originated from this, signifying that someone had a good night’s rest. The word daisy also made its way into other slang words and phrases.

Do daisies sleep?

Daisies open their flowers during daytime and lower their petals during the night. Easy, because at night daisies are resting, sleeping, and they wake up again when the sun comes up while a few other species of flowers close their petals instead.

Why do daisies close at night?

At night the insects that pollinate most flowers are dormant and closing the flower keeps the pollen dry and contained. Some flowers that are pollinated by moths or bats do the opposite and only open at night.

Why does daisy flower open and close?
