ok cool, um why might i ask?

well yes but actually no

oh my god your right-

A lot easier to push someone down too! Loads of benefits!

Stairs you usually only use your feet to climb. With ladders, you need to grab the bars above you for stability.

Slide down your stairs when they are in their normal use and slide down a ladder when it's in their normal use (directly upright but a little slanted). See they're different.
