Riding a bike is so risky, you should never ride it on a road or under a tree, whether going to work or just riding around for fun. You could get hurt or killed. Be really safe and give up cycling altogether. Also, don't go for a walk because pedestrians get hurt and killed all the time. Cars are really dangerous too - have you seen how many accidents there are on a daily basis? Just turn on the radio during rush hour. I'd say working from home is the way to go, but make sure your smoke detectors have batteries and the doors are locked at all times.
