I mean for myself there are things I do that can’t say have rigorous scientific proof but usually have some basis and personal experience that it works for me. I mean if I found prayer effectively solved problems for myself I likely would not be athiest even if no studies showed that. I take fish oil because an eye doctor recommended it for dry eye and my personal experience is it helps but I have no study to back it up. I take a vitamin supplemented cod in particular because my doctor said I needed to get more d and that was the only way I was willing to get it. I take a diosimin supplement because when I had a bad hemmoriod it was prescribed to bring it down and I found out it was also prescribed as a profolatic at lower doses so I basically self medicated. Seems to help. When I talk about the effects of these on myself I should mention im bad at consistantly taking them and when I don’t I notice stuff. I like long baths and it seems to have a variety of beneficial effects especially with sleep and stuff so its good when done to be done at night. I think I have seen studies but not things I would consider rigorous. I mean. I really don’t think I have anything that does not have some basis and im pretty aware of how weak or strong the basis is of most things I do.
