Home exercise still possible if one considers yoga/pilates/elliptical cycle and etc. In Malaysia, we are still allowed to exercise outdoor.
N95 masks in combination with face shields work best because infections can transmit via tear ducts. However, due to inadequate N95 mask supply, regular masks are mandated in my opinion to psychologically calm down the public. Excessive fear kills quicker.
Singapore did a way better job at preventing school-based transmissions. Anyway, this pandemic sped up the transition into web-based education for those affected by severe bullying issues.
