I think everyone in this thread is right. We seem to be disagreeing over the use of the article ‘a’.
The OP said it would be “100% profit” which is correct. This is in the general sense that they paid nothing so that any price would be pure profit.
You’re talking specific numbers, hence it is “a 100% profit”. Depending on the price it could be any percentage like “a 213.75% profit”.
You’re both correct! It’s funny how English works, right?!
I don’t disagree that people who are overweight will feel hotter. The rainy season makes it feel hotter than just the temperature here, too. Buildings here are probably more poorly insulated, too.
Every home I have visited in Japan over the past two decades has had A/C units. You may be right that in regions where it is very cold an A/C unit may not be necessary. However, as heat pumps are one of if not the most energy efficient ways to not only cool but also heat a home, I wouldn’t be surprised to find them even in colder regions.
Add on the fact that houses in Japan are generally considered a depreciating asset, so until recently demolitions and new construction were favored over renovations, I stand by my first statement.
Additionally, every place I have ever rented has come with at least one A/C unit, and additional holes are predrilled in other rooms so that split systems can be installed.
Conversely, AC is much less common in places like France and Japan, and it’s not just because they’re too cheap.
I assure you that practically every household in Japan has an air conditioner these days. Maybe not some decades ago but things have changed, including the climate. And companies are legally required to keep offices at no higher than 28°C, too.
Not uncommon here in Japan, either. People leave phones/handbags to reserve a table when they go to order at the counter (at a cafe etc). It’s nice not to have to constantly worry about theft as much as other some countries. Not to say that there is no crime because that’s not true.
