Just saw the movie "Dragon Ball Super Broly". Early in the movie Bulma said she was gathering the dragon balls to wish to be 5 years younger. When asked why not 10. She said she didnt want to be obvious she had work done. By the end someone else got the wish so she never got younger. Which got me thinking...what if she did and Shenron misunderstood her wish so made her 5 years old rather then 5 years younger.
