Germs everywhere in the air

Being sick since thursday till today. Work place is full of germs. Even opening the windows and airing the area doesnt help. 3 of my collegues are sick but only 1 of them need to be on sick leave while the others are still able to make it to work..Poor me whom immunity is super low, got the germs and fell sick after surviving for 4 days with them. How does one build up immunity??? Self discipline! Janice Tan, can u please be more self discipline and stop being lazy? Eat less meat, eat more fruit, do more yoga, stress lesser, relax more, eat less fried food ...NO NO NO NO is NO FRIED FOOD AT ALL....for at least 3 months...U will grow slimmer, prettier, better health and look more radiant...YES JANICE TAN....YES...I am strong, healthy, slimmer and prettier nowadays....
