Real case: it is dangerous to drink too much coffee

In 2007, a teenager in the UK was taken to hospital after drinking too much coffee. Seventeen-year-old J.W felt hot and began to hyperventilate after drinking seven cups of double espressos coffee in a sandwich shop. The student, from Steinley County in Durham, was taken to North Durham University Hospital where doctors confirmed she had too much coffee. After she recovered, she warned others about the danger of drinking too much coffee. She recalled that after drinking seven cups of double espressos coffee, she began to laugh and yell at the customers in the store for no reason. "I felt palpitations, my heart was beating so fast, I thought I was going into shock," J.W said. She became feverish and short of breath after being sent home by her father. She described the scene like this: "I shuddered all over, sweated a lot, had a fever, and was overventilated. I don't want this to happen to others again. I just want others to learn from my mistakes." The 17-year-old girl went home after several hours of observation in the hospital. Later, she could no longer see the coffee. His father said he didn't expect her to drink so much coffee. "I have always stressed to my children the importance of drinking coffee in moderation." But J.W is overloaded. Anything excessive can be harmful to human health, including coffee, food, vitamins, money and even love.
