Great review as always, thanx
One small typo on the 2nd site, last sentence. There should be superior.
…not the 1st typo in this exact word … I have two guesses for the reason:
1st: superior in Greek = ανώτερος [anóteros] …phonetically close prefix an ≈ in…. or
2nd: you work too hard (almost every day one YouTube video and one review + other activities) … you should rest more, not just work … in Slovakia we have a saying… work is not a rabbit, it will not run away, it will wait at you … 😊
thank you! No rest for me 🙂
Great work, thanks!
