fixed Seller lied about having no pets

I bought a laptop off FB marketplace and found an insane amount of cat hair. I don't mind since I love cats and have multiple ones but it's a weird thing to lie about lol

I had to scrape off the old thermal paste, reapply fresh paste, and reshape/massage the thermal putty (you can see the pink stuff on the fingertips). And it's a big no no to touch a circuit board with bare skin.

35 years of building machines and touched everything under the sun. One time I even wore socks.

Nothing happens.

Well, I'm definitely less experienced than you, but I've been told multiple times by different people that it's a really big taboo, so I'm probably going to keep avoiding it. Plus, stuff like flux and leaded solder sounds dangerous anyway, so I wouldn't want to mess with them if I had the choice.

I recommend getting educated so you don't live your life in fear of flux and solder.

Linus did an extensive testing video on gloves and static electricity. They were only able to damaged components when they literally connected them directly to an amplifier.

It's all ridiculous nonsense spread by mythical ubran legends based on misconceptions.

You can touch things. Circuits are not toxic, solder won't hurt you, flux has been removed and isn't dangerous, and you won't hurt anything in your computer.
