Always Wear a Helmet
When my dad was younger, he used to sell motorcycles for a living, and rode them frequently as well, never wearing a helmet. One day, he decides to wear a helmet for whatever reason. That day, a car t-bones him, he goes flying from his motorcycle and skids across the road.
His helmet got sanded down from the impact and subsequent skid on the road. Despite having major back, shoulder, and hip problems to this day, without that helmet, he probably would have ended up as a red smear on the road Story credit: Reddit / SwipeRight4Wholesome
