I don't carry a gun but I almost always carry a fog style pepper spray on me. I used to use Fox Labs but UDAP made an even stronger pepper spray, pretty much the strongest legal to carry, self defense pepper spray. UDAP is famous for their bear spray line. [1]
If you work at an office or startup, I recommend purchasing a fire extinguisher style 1-5 pound pepper spray due to the increased range and capacity. [2]
A note of warning though: I have sprayed myself on the arm with the weaker of the two, the Fox Labs spray - mind you, outside with good breeze. Just a spritz. Well, my arm pretty much burned for two days straight and if I went inside, it was hard to breath due to the constant smell. It would not rinse off my arm with water or milk.
If you have poor accuracy, go with the fogger style. Stream style pepper sprays have longer range but are harder to hit vitals and create a barrier. Fog pepper spray can pretty much be sprayed to create a wall of pepper that no one will able to go through without being blinded and severely impaired. So it can be used to prevent an attacker from heading towards you, even if you can't reach the attacker.
I am not saying pepper spray is better than a gun but it requires almost no training and can save your life if used properly. Every office should have some along with a fire extinguisher.
The problem with statistics is that people like to ignore them in when they don't support their narrative.
If you lived your life entirely trying to avoid things with an incredibly minor chance of happening to you, you would stop living life. You a much higher chance of dying in a car accident, choking to death on your food, or in a bike related accident. Yet I drive, eat, and ride my bike.
Total umbrella statement applicable to anything, ranging from fortunate events (e.g. winning a lottery) to unfortunate events (e.g. crashing your car).
The problem with statistics is when you become one.
