7/17/23 another shower, this time after more than an hour on the rowing machine, covering the equivalent of 10 km on the water and dripping sweat. Did not do the moisturizer today and did not wash my hair. At some point I will need to wash my hair, but for that I will need to take a shower in the morning or early afternoon when I still have time for my hair to air dry because I do not use a blow dryer.
