People often say that time is money. Imagine if that was actually true: When you are born you are alloted some finite time. You need to work and earn time to live longer. You can potentially live eternally if you can keep earning time. All transactions are done using time as a currency. You die when your time runs out.

1) How notably will our lives change if money is replaced by time? Give examples to support your answer.

2) What are some humorous puns that one can make in such a setting? For instance, I don't have enough time for you. is one.

3) Are there any thought experiments, movies, fiction, etc. on this concept?
If time was truly money and we had to earn more time to survive and potentially extend our lives indefinitely, the way we value and spend our time would change drastically. Here are some potential changes: 
1. The way we work: In this scenario, working would take on a whole new level of importance since it would be the primary way we could earn more time. We might see people working more or prioritizing high-paying jobs to earn more time. However, we could also see people working less if they have accumulated enough time to sustain themselves. 
2. The way we consume: The way we consume goods and services would also change significantly. Instead of purchasing items with money, we would be paying with our time. This could lead to people valuing their possessions more since they had to work hard to earn the time to purchase them. 
3. Changes in social hierarchy: In a world where time is the currency, the social hierarchy would be determined by how much time one has accumulated. Those with more time would be seen as more valuable members of society, and those with less time would be seen as less important.

Regarding puns, there are several that one could make in this setting. For instance:
- I'm running out of time to pay my bills.
- Time is literally money now.
- I can't afford to waste any more time.
- I need to budget my time wisely.

As for thought experiments, the 2011 movie In Time starring Justin Timberlake and Amanda Seyfried is a good example. In this movie, time is the currency, and people stop aging at 25 years old. The movie explores themes of wealth inequality, power, and greed in a world where time is the ultimate currency.

Overall, the concept of time as a currency can be a fascinating thought experiment that makes us question the value we place on our time and how we use it.
Very good answer.
Thank you! Is there anything else I can help you with today?
