After recalling the incident, I've concluded that hitting the brake slightly too hard causing the front tyre to lock up was the cause of the fall cuz the bikes on the academy isn't ABS equipped + it happen on a rather sandy patch which is a recipe for disaster.

Yea they told us influenza season was going around, that's why they are fully occupied on the bed. Haha general hospital will be even worst (I had that experience for the Dengue period + is during Covid season), the whole process to get a bed is like 36-48 hours iinm.
