There is an error in "physical effort seem less difficult (to me) ....". That should be either "physical effortS seem ..." (the better choice as it aligns with plural use in French), or "physical effort seemS . . ".
It may be regional difference, but some of the turns of phrase in the English script would rarely, if ever be used here.
PS I note that the use of 'efforts' was questioned previously, and was changed to effort. "Efforts" is definitely acceptable as a plural - a quick check of Collins dictionary confirms this.
