Invented by Ben Franklin lighting rods are just what they sound like they are rods on a roof to take lighting instead of it hitting a house and burning it down.
because the lighting rods helped them cross the river or an ocean
Or technology is very advanced that the structures are reinforced internally. We also have lightning rods, which attracts lightning and is a safe way to prevent lightning strikes
So buildings don't catch on fire

Yes, lightning can strike the same place multiple times. Tall structures like skyscrapers and lightning rods are likely candidates for repeated strikes due to their height and conductive properties that attract lightning.
Rods are photoreceptor cells in the retina that are responsible for vision in low light conditions. They are sensitive to light and help us see shapes and movement in dim lighting. Rods are not sensitive to color and are more concentrated around the periphery of the retina.

Vertical rods are long, slender pieces of metal or other material that are positioned in a vertical orientation. They are often used for structural support, reinforcement, or as part of machinery or equipment. In construction, vertical rods are commonly used in reinforced concrete to provide strength and stability to structures.
Sponges protect themselves with spikes in their body.
