Why have medicine, dentistry, and oriental medicine become even more popular compared to 10 years ago?

Even in 2015, medicine, dentistry, and oriental medicine were popular, but they weren't at the level they are now. Even just looking at university entrance scores, medical departments were lower than they are today.
The number of people over 40 attempting the CSAT to enter medicine, dentistry, or oriental medicine was also much lower 10 years ago than it is now.
In 2015, information sharing was already fine due to the development of the internet, and work-life balance in corporations is actually better now than it was then.
What is the reason why medicine, dentistry, and oriental medicine have become even more prominent recently?
