I don't understand Intermittent Fasting from a digestion point of view. The fast usually starts when you end your last meal, however you'll be busy digesting your food for hours, can those hours really be counted as "fasting".
Fasting, to me, begins when all previous meals are digested
What kind of financial news do you read to inform your judgment on larger issues? I feel I tend to get overwhelmed with short-term and often irrelevant news on finance/global economics/markets with my current curation routine, as I read daily sources that focus on immediate markets news with little in-depth substance (Reuters/WSJ/Bloomberg...)? Do you also read more in-depth analysis, featured in weekly or monthly magazines such as The Econommist or other?
You specifically refer to Undergrads as an example of hustle culture in the US, this is true as it's mostly bred into them by the all-achieving american mindset of making a name for oneself ("I'm not a millionaire...yet!"). As a post-prepa engineering school graduate myself, that can hardly be compared with the undergraduate culture we have here for top talent. We have a far stronger culture of learning theoretical sciences in depth (Prépa) and French engineers/quants are well-known worlwide for having a strong academic background in math/physics. We specialize later in school for most people, while early "tinkerers" or programmers may have chosen other paths (IUT/Epitech/...) instead. Not to say one is better than the otheer, but you'd better build a strong academic track before you're 23 (Prepa -> Top school = right signal for employers) or risk experiencing a glass ceiling regardless or your actual skills. The culture is there among students but the corporate hierarchy is still stratified at the top. Regarding the expensive top business schools, a cushy CDI remains the best way to pay off your student debt if you took out loans in the first place. Overall as a young educated graduate in France you'll be bound to expect some struggles as you try to swim against the current. As I remember the words of a dual-degree graduate from Stanford/polytechnique (Antoine D.), "«En France, j’ai appris à apprendre. Aux Etats-Unis, j’ai appris à rêver». There's room for both here but it won't be easy
