I'd say it's been a productive day. I didn't go for my regular exercise walk, but I reckon I walked even longer than normal back and forth, up and down stairs today. So, yea, productive day

It is tempting to miss out the purpose of exercise. You didn't go for your regular exercise but you did another kind that reminded you that you've got calves!

I didn't realise that I had been on my feet for more than 6 hours straight with no rest. I started noticing it when I felt a dull ache of fatigue around my calves which forced me to sit down and take a minute.
