I can't get motivated to take regular showers

Today is December 5th and I have not taken a full shower since October 26th. I wash only my armpits at least once a week and apply deodorant to get rid of body odor. I went the whole month of November plus without setting foot in my shower. I used to bathe once a week or a few times a week but I have lost nearly all motivation. One reason is because it takes me too much time to bathe. I'd much rather be doing something fun such as video games than take time to bathe. I have never bathed every day and I refuse to. I still smell good for a couple of days so bathing every day is useless! Some people take a shower, go running, and then take another one. I think this is absolutely ridiculous and unnecessary. If you have to bathe, just take one after running. Doing it before is just an absolute waste of time and recourses!!! I saw someone say that only cavemen bathe once a week, but I don't care because nobody has complained about it. I usually was my armpits after they begin to smell. I wear a hat when I'm working since it's part of my uniform and nobody can tell my hair is dirty. I am a nearly 24 year old man. I never liked bathing regularly as a teenager, but I usually did not go this long without it. On average I have been bathing nearly once a month. I probably haven't taken more than 12 showers if that in 2020, and I have not gotten COVID-19. I want to do what is fun in my free time and not waste my life bathing.
