About a year earlier I successfully had been suggested that I should sleep in a tight Under Armour compression shirt instead of the lycra shorts I till then always had worn in bed at night, and intentionally I should have done the same this night. But a week before I had been running in some very tight shorts, and they had been compressing my upper thighs so much that my skin just below the shorts had bulged so much that this part of my legs had rubbed each other when I had been running. With the result that I now had two bloody patches on my inside thighs.
