Where I live, the places that do blood donations, also do plasma donations. The process is longer, but is otherwise a similar experience. And since plasma is extracted from blood, it is not entirely wrong to argue that people can get paid for blood donations in the US. It is not accurate, but I would argue the statement is probably based on a truth.
The worst thing is: you can’t even put an int in a json file. Only doubles. For most people that is fine, since a double can function as a 32 bit int. But not when you are using 64 bit identifiers or timestamps.
