Not even the glaring, but hitting them and them dropping dead later on - days, weeks, months, even years. There’s alleged pressure points that have a “delayed death touch” effect, according to some very old MA sources.
Some are actually real, but not as they envisioned - bruise someone’s heart, and it can take about 6 months for a heart attack. Rupture someone’s spleen (not outright, but a small tear) and they could drop dead within a few days. Give someone a concussion and they can sometimes go asymptomatic for a period. Kind of hard back then to disprove the delayed death touch. People also died from natural causes within a relatively short time period, and the other person could claim it was his plan all along. Modern medicine has explained some of that and thankfully prevented a lot of it.
Then there’s herbs that people took and got better. Well, some illnesses resolve themselves. Kind of like some old wives’ tales about pregnancy and speeding up going into labor. Jumping around won’t induce labor. But if you’re jumping for days and then go into labor, sure, it was the jumping

Had nothing to do with she was going to go into labor anyway.
