Even the iconic Bruce Lee appreciated the importance of on vital points (急所 Kyūsho in Japanese) in martial arts. This can be seen in book 'Bruce Lee - The Tao of Gung Fu: A Study of the Way of Chinese Martial Art' (Published some years after his passing in 1997).

Focusing strikes to the weakest point in the body is not only effective in combative situations, but it provides a maximun effect within a enconomy of effort.

I have transposed the points from his book onto a skeletal chart for ease of understanding.
