I would check on it if you are concerned. It can’t hurt to check and if you find something that needs to be addressed, now you know and can work on fixing it.

My boss has sleep apnea and did a sleep study. It turns out he was having roughly 80 episodes an hour where he stopped breathing. They also found that his heart rate was jumping up to 135 bpm during these episodes, as well as his cortisol levels rising way above normal.

I would say it is probably good to know the severity of the condition, as it might be good to know how treatment might need to be. Having your heart rate spike like that is not good, and it means that he will have more monitoring and checking in with his doctor as he adjusts to and uses his CPAP machine.

I have this and I always struggled with math. I was terrible at mental math and I wanted to be better. I changed all of my clocks to military time so I had to do a very small and easy mental math problem if I wanted to know the time. I started to get better at it and now I am better than most people I know (not by a whole lot, and it does still take me a while to get more difficult problems done). I now enjoy trying more difficult problems just for fun. I also developed some interesting methods to chunk problems in my head so they are easier to manage.

It’s not about hours of practice. Small incremental changes over time can be a better way to go about it.
