The main reason that White throws off the covers each day after four hours of shut-eye is that she is just positively giddy that she will be working. Her whole attitude seems to be one big reason for her longevity — she is a very positive person overall. She even told Prevention Magazine that not taking herself seriously has been an important part of her staying healthy. She also credited staying active both in body and mind as a big key. 

Sometimes the secret to longevity is also to have some luck and good genes. There are those who live an extremely healthy lifestyle that pass on at a young age due to other factors, and others who eat foods that many would deem unhealthy and live beyond 100. The important thing is to make the most of one’s time.

Since White is closing in on turning 100 in January 2022, it’s pretty apparent that this lack of sleep has not had a negative effect on her health. She still has all her faculties and health. While it might not be great for everyone, it certainly works for her. In this case, only be like Betty if you are staying healthy, too.
