They Travel with their Own Blood
On the road, some superstars have a reputation for being ogres. Most people have witnessed the riders that performers occasionally add to venues, requests for luxuries that might make them appear diva-like. They ought to travel like the royal family, who always bring their most critical belongings—like blood bags—with them.
Queen Elizabeth, Princes Charles, and William all travel with a sack of their own blood on hand in case of emergencies. Duncan Larcombe, a Royal expert, says this. In case a transfusion is required, the Royals bring their doctor and a bag of homemade beer.
The Queen made around one state visit year during her busy years, while Prince William traveled more extensively. Since blood only has a 42-day shelf life after being bagged, they were likely purchasing new supplies before each and every journey.
