You have a bath once a year? I think you are lucky, I haven't had a bath since I was 6, when I stopped fitting in the tiny bathtubs in canadian low income houses. Especially not now; bathtubs that would fit a 185cm obese woman seem to be extremely rare and expensive
you should try bathing using one of those body washes for men that mix shampoo and conditioner and bodywash instead of a bubble bath mix, I hear they get pretty bubbly and they wash your body well too.
