People did some gardening work. They had some free time. Did a great job. Yet they forgot one thing. Really two.
One is to wear gloves when gardening. Two is to wash hands and/or shower afterwards. Why? If one’s skin came in contact with Poison Ivy – the oils can be washed away within an hour in order to not be infected.
Ushmartem Meod Nafshotechem – Torah says: you shall very well guard your soul.
