When I was a kid I used to eat my boogers a lot and my mom used to get after me about eating my boogers and one day when I was in the doctors office I started to eat my boogers and my mom tried to stop me.
The doctor said that it was actually okay and good to eat your boogers because the boogers contain some good bacteria that helps to boost your immune system.
I no longer eat my boogers because I now find it gross but I do remember I didn't get sick as much when I was a kid and eating my boogers.
Whether that was due to me eating my boogers or not I'm not sure but eating your boogers certainly won't hurt you but I couldn't do it now because it grosses me out.
