You can't prove the non existence, but you can be very sure about some things. Megalodon lived near the surface, because it liked warm water(AFAIK), so it's likely that if it wouldn't be extinct there's a high chance that we would notice it, since Megalodon was kinda big.
I use the flatpak version on my laptop and version from the repositorys on my main pc. So i either have to just update a flatpak or just do a full system update.
That isn't even the slightest true. There hasn't been a single moment in my life where I was in the situation that I talked with a woman outside of them being my classmates(and even then those conversations were mostly questions and the rest being things I or them said in a bigger group). I never had a real conversation with a women so there's absolutely no chance that I missed flirting since there was no situation where flirting could have occurred.
Sitting here writing this I realise how bad my social life/skills are.
Or do it like me. You can drink more if you drink at least the same amount of water. Of course this has its limitations. At some point drinking water just reduces the headache the next day but doesn't makes you think clearly.
That's it. If you're bulking eating 3k calories a day is normal. The more muscle you get, the more you have to eat to maintain your form(or eat less to effectively burn body fat). Of course, you want to eat healthy, meaning that eating 3 burgers a day is probably not the best thing, since it has a lot of fat in it.
We have bought a HP printer about maybe 7-8 years ago(don't know the model) and it just works. No annoying drivers, no "can't do shit because of low ink" and you can even use non HP ink cartridges. The only problem is, that sometimes the scanner doesn't work properly so that the document is literally unreadable. After cleaning the scanner glass 7 times it may work. Luckyly this doesn't happens very often.
