According to Vital Wellness, the benefits of having a hobby include:
It's an opportunity to meet new people
Stimulates the mind
You have fun!
Hobbies are not just for sad, lonely or lame people. Did you know that Amanda Seyfried and Ashton Kutcher knit, Angelina Jolie collects daggers, Leonardo DiCaprio collected Star Wars figurines (which he sold for charity a few years ago) and apparently, Taylor Swift likes making snow globes.
