Society also treats people differently.

If you’re a 25 year old woman, you likely have a lot more standards to align with than a 75 year old man.

At some points in our lives we rebel (teenage kids with dyed hair, or piercings or gothic clothing) from these norms…at other times we basically ignore convention as it’s too hard and you can’t be bothered (cold winter days, soon after an operation, in old age).
