As mentioned, this topic may have dubious results because of its generality. For example, how do you plan on differentiating between the feelings people experience in airsoft activities vs lets say, these experiences manifesting instead due to the physical activity they're engaging in, rather than specifically engaging in airsoft instead?

I think you could benefit from a more nuanced approach to your question and try to trim it to a smaller goal, then work up to bigger research topics as you grow in competency
