Did you make any actual attempts when you were younger? Maybe it's more that it was passive ideation back then. I think passive ideation is much easier- even enjoyable- the idea of being dead and free without having to actually plan and go through the process of it.
When you start actually thinking about what you're going to have to risk and what you may have to put yourself through to gain release, it becomes a whole lot scarier I think. Plus, sites such as this tend to urge us to be cautious I think- we're more aware of attempts failing and the aftermath. Maybe it's better in terms of keeping your nerve to be naive. Not wise in the long-run I feel though. I think it's better to research why attempts fail so we give ourselves the best chances of a clean exit.
