medical questions. First question, Dr. Jen. What types of behaviors or precautions would you continue to practice even after herd immunity is reached? This is an interesting question. You have to ask are you only talking about sars-cov-2 or infectious diseases in general? This isn't the only bug out there. This short answer, it's to be determined. I suspect that we will see a lot of people continuing to wear some kind of face covering in public crowded areas because we've seen a demonstrated benefit in transmission rate reduction with this particular virus. Hand hygiene, I think that should -- that's a safe one we should be continuing. All the other things, hopefully the physical distancing will just be short-term and temporary. All right. Next question, noncovid. My resting heart rate averages 80 to 99. Is this normal? Should I see a cardiologist? Yes, it is normal. Fun fact, I am the daughter of a cardiologist. I grew up hearing about these things around the dinner table. Normal heart rate is 60 to 99. Below 60 can be a sign of something. Above 100, tachycardia, very commonly seen with fever, thyroid issues. Keep an eye on it. Don't make it a science project. We think average is what? In our minds what? It depends on your age and fitness level. The more fit you are, the lower your heart rate is. So this one here is probably beating about I don't know, 20 times -- no. If I had to guess, Amy, I would say you're in the low 60s. I am usually. Mid 60s. That's when she's worked up. My work here is done. You're right. Keep submitting your questions to Dr. Ashton on her Instagram @drjashton.
