"But that's an other topic altogether..." You misspelled another.
"You read a bit before making up an hypothesis..." A should replace an, since the h in hypothesis is not silent.
"Store where they sell cloths..." Clothes, not cloths because you are talking about clothing not fabric.
"Would you trust his judgement? Of course no." You used no instead of not.
"Scientific answers are worthy of thrust because..." Trust not thrust, you made this mistake multiple times.
These are only a few errors I found in this disgusting post. This post should be moved to the odds/ends section of TT and not in tips/instruction, because it offers no help in tennis.
