Wow! The Japanese scientists are really doing a great job to come up with such technological advancement inside a supercomputer which shows the direction of flow of gases involved when people cough. This will also solve more problems as regards to people who don't cover their mouth when they cough most especially when they are communicating with other people in an enclosed environment.

Thanks for sharing this great post with love from @hardaeborla and I hope you have a great day ahead
