 we've had to face with COVID. Wow. Now, Doc, I find that, you know, obviously it makes a lot of sense. You're right. Both the isolation and the infection can be a cause for this PTSD. When you say you've seen an increase following COVID, was it really like a marked increase, a very spiked increase? Would you say like the majority of people that went through COVID are now experiencing PTSD or is it a small percentage?
