i usually take a bath at night before going to sleep. when my aunt found out about this, she advised me not to because it is bad for my body. i reasoned out that it makes me at ease feeling clean and fresh before going to bed. she told me that i may be a hard headed now but when i get old, i may regret doing this because it will have some effects on the future. what do you think?? is she telling me the truth??
