Don't practice typing faster with your current method, because you already have for 30 years. Rather invest some time to learn a better method.

I learned touch typing within a week on holiday vacation with a software similar to this website: https://www.typingstudy.com/ (Young me felt very proud of being able to type like dad.) Once you have invested the time to learn the basic movements, you will become accustomed to them naturally.
