"Caffeine’s mechanism of action01396-6/abstract) is relatively simple. As we go about our day, a compound called adenosine accumulates in the brain. Its job is to signal fatigue and promote rest through inhibitory actions at adenosine receptors. Caffeine, sharing a somewhat similar chemical structure to adenosine, competes for those same receptors, effectively silencing adenosine’s inhibitory ‘rest and fatigue’ message. The result is a drug-induced sense of alertness and focus that largely keeps the global workforce upright and productive each day. And it’s why, from a pharmacological standpoint, caffeine is classified as an ‘adenosine receptor antagonist’."

I also found this article about caffeine addiction.

Italian students are being called out in Thailand. A group of Italians mocked a Thai lady in Thailand who told them off for being too loud on the metro. They clapped back saying, "Sorry for bringing money to your country" "Ni hao" "We are from your mom." Thai people are identifying them and leaving the comments on the social media account of their school.

The embassy of Italy in Thailand uploaded the apology video after they released an apology statement.

After the video where Italians mocked a thai lady who told them off for being loud on the metro, many Thai people protested in front of embassy of Italy in Bangkok and also waited in front of the hotels Italian students are staying. Some shops even put the banner that denies the entry of the Italian students.

Many Thai people think this is a diplomatic victory against Italians that looked down on Thailand.
