A new semester means that I have to do everything I did during the summer break plus taking courses. Today, I took three courses between 9am to 5pm, and tried to fit my rat hippocampal culture in the limited time. In the end of the day, I was as tired as I could imagine but achieved all the missions I had to do. Thanks Che for the delicious dinner, and the lunch box for tomorrow. Let's have a good sleep and prepare for all the good and bad things of tomorrow.
