A ladder is a vertical or inclined set of rungs or steps. There are two types: rigid ladders that can be leaned against a vertical surface such as a wall, and rope ladders that are hung from the top. The vertical members of a rigid ladder are called stringers (US) or stiles (UK). Rigid ladders are usually portable, but some types are permanently fixed to buildings. They are commonly made of metal, wood, or fibreglass, but they have been known to be made of tough plastic.
Rigid ladders are available in many forms, such as:
Rigid ladders were originally made of wood, but in the 20th century tubular aluminium became more common because of its lighter weight. Ladders with fiberglass stiles are used for working on or near overhead electrical wires, because fiberglass is an electrical insulator.
For safety, a rigid ladder should be leaned at an angle of about fifteen degrees to the vertical. In other words, the distance from the foot of the ladder to the wall should be about one quarter of the height of the top of the ladder. At steeper angles, the ladder is at risk of toppling backwards when the climber leans away from it. At shallower angles, the ladder may lose its grip on the ground. Ladder stabilizers are available that increase the ladder's grip on the ground. One of the first ladder stabilizers or ladder feet was offered in 1936 and today they are standard equipment on most large ladders.

i'll throw fear to the wind without a care
cause i don't know who you think you're fooling from there
if i could i would shoot an ear to ear grin
i'm looking down on you while you sin and sin and sin
and all i see are people climbing ladders
what a great way to kill yourself faster
leave your own dreams at the door all beaten and battered
what a great way to kill yourself faster
go on and kill yourself faster
kill yourself faster
go on and kill yourself
i'll throw fear to the wind without a care
cause i don't know who you think you're fooling from there
throw another stare at them make them believe
