I purchase Pulse Oximeters few months ago start testing my blood oxygen level. I heard when you get Covid-19, your O2 level in your blood goes down. I think it tis good indicator where your health is.
In addition, I check my weight, blood sugar, temperature and blood pressure in the morning. I cannot afford to get sick.
I am publishing newsletter every Wednesday.
