I am going to be deposed as an expert witness in a medical malpractice case. It can be stressful to be in that position. So, beyond reading (and re-reading) documents, articles, etc, what did I do?
Get on the treadmill! I got my heart rate during intervals briefly up to 176 (supposedly higher than a 55 year old man can go!) PS: Don’t start exercising trying to get to that heart rate. It took me years of regular exercise to get there. My resting heart rate is now in the low 60s, which may even mean I’ll live longer.
The stress flows out along with the sweat, Onwards!
