Good point. Now it does make sense. I know the secret to the perpetual motion machine now.

Okay so individual stocks then. But the advice is for index funds I think. But good on you if it works. I wouldn't try to predict individual stocks personally, too much stress and probably won't do it better than randomly guessing.

Thanks, something like this is indeed already interesting, especially with the return on investment calculation so I'll check it out. But to be slightly more directed at what I wanted, I meant a paper/article researching how much it would cost and it would save to have 90% of the trips in a society be with public transport. I understand if that is not something a lot of direct high-quality research has gone into.

You seem quite invested so I have a question. I have learned that protein fills more and therefore reduces appetite. Won't a protein shake be a relatively healthy option which reduces snacking and overeating of less healthy meals? This has also anecdotally been my experience but I haven't done it very much.

Why do you look at your investments? What do you do with the information? I don't want to predict the market and I can't. Looking at it is more likely to make you panic buy/sell than make you do anything useful. But I'm curious why you don't agree with the advice.

It's a lot more backed by the faith that if you don't manage to get some you go to jail.

You ask if he agrees in your post, he gives an honest and normal answer, and you call him a joke? That's not much better faith than what you're complaining about.

(Paper) money is practically actually valuable because you need it to pay taxes. Gold, diamonds etc you could do without. Of course there is more nuance but taxes force people to value currency and therefore also accept it from others (because you need some of it or you go to jail), which gives currency the circular value.

Would this for you include accomodation? And do you think you'd prefer a lot of control over that or just a general view? Like a searchpage that has a budget, a starting location and a departure and return date. This would return only the places where the train/bus/flight + hostel/hotel would fit in the budget.
