Science Vs did a great podcast episode on mass shootings . I don't know how much access to mental health resources and suicide prevention would help but it's one of those things were there is no downside to expanding access to mental healthcare. They talked to a researcher who studies mass shooters and when it came to the question of mental illness and they found

"roughly one in ten of these shooters is doing it because they’re psychotic. Other research finds similar numbers – sometimes a little higher. Generally speaking, though, the majority of shooters are doing it for some other reason besides psychosis.

The mental health issue that really stands out here is this: About 70% of the shooters were suicidal. In fact, the probability that a mass shooter dies by suicide after the crime is much higher than for other kinds of murderers."

When Jillian looked closely at the period leading up to these men’s crimes, she realized they had often reached some kind of crisis point.

Usually it was because they just had their wife leave them, or they just lost their job, or something dramatic happened in their family, or at school – where it was kind of the final thing that pushed them over the edge.

So these are… they’re angry suicides. What we see in these perpetrators, and there’s one sister of a perpetrator who put this particularly well for me, she said: My brother, he was saying, it was all about ‘What's wrong with me, what’s wrong with me? Why don't I fit in? Why don’t I have the things in life that I thought I would have? What is it about me?’

And then she said there was a switch. And it became not ‘What's wrong with me,’ but ‘What's wrong with everybody else, and whose fault is it? Who made this happen to me?’

And so in some cases it's women, or it’s a religious group, or it’s a racial group. They kind of choose a target that represents their grievance with the world–who is it that they blame."

I get cold very easily and get numb fingers too. The best thing that has worked for me for hiking in the cold is something like a pair of outdoor research gloves that have the tech touch so can use my phone, paired with some black diamond mittens that fit over them. I have yet to find any gloves that will keep my hands warm and still can use my phone.
