You see it, you know it’s inside all of us, and you assume it must be a high-risk route every time it shows up. The real story is narrower. HIV risk from

Many common germs lose the ability to infect at 60°C/140°F held for minutes, while true sterilization uses pressurized steam at far higher heat.

Follicles can regrow hair if the root stays intact; scarring that destroys the follicle usually stops regrowth. Shedding and thinning can make you feel stuck, stuck between hope and worry. Some follicles recover once the trigger ends. Others can’t, especially when scar tissue replaces the follicle. This page explains what “follicle damage” means, how to

Fish oil can lower triglycerides by 20–30% for many adults when it delivers enough EPA+DHA, with bigger drops at higher starting levels. High triglycerides can feel sneaky. You can eat “pretty well,” stay active, and still see that number pop up on a lab report. Triglycerides also swing fast: a week of extra sugar, alcohol,
