Feeling my age

I don't know how much of it is simply the activity level of the weekend, between the 50-miler on Saturday and the chore yesterday, but I feel somewhat lethargic this morning. I hope I haven't picked up some sort of bug from the old carpet and padding - variously soiled throughout the decades and deteriorating - that I took up yesterday. I made sure to wash my hands often, but am sure I was breathing in some less than ideal material. I didn't even think to don a respirator. The work was not as bad as I thought it would be, even though it was every bit as much of an individual effort as I expected, but I'm still a pretty sore old dog today.
