Almost everyone killed by lightning in the United States is a man. Since 2006, 80% of lightning victims were men. All seven people killed by lightning so far this year were men. This brings us to the only possible conclusion: men are stupid.
The seven men who died from lightning this year were fishing, closing car windows, riding a motorcycle, picking blueberries, roofing a car dealership, and two were near a tall tree when they were struck and killed.
Why are men the likely target for lightning? As demonstrated by this year's data, men are more likely to spend time outdoors by virtue of activities.
As the Capital Weather Gang points out, men are more likely to die at the mercy of lightning as men are "unaware of all the dangers associated with lightning, are unwilling to be inconvenienced by the threat of lightning, are in situations that make it difficult to get to a safe place in a timely manner, don't react quickly to the lightning threat."
In other words, lightning mostly kills men because men think they're invincible and don't pay attention to common sense.
