What is the difference in the way people spend their free time nowadays compared to 20 or 30 years ago?
Well, I think there have been lots of changes over the last few decades. In the past, people did a wider variety of activities both in and out of their homes,whereas nowadays, so much new technology has been created that almost everything can be done on our smartphones, like playing games, streaming movies or reading. As well as that, different ways to chat with our friends have been introduced, so even though we spend less time together, people are actually more connected, so they spend more of their downtime chatting with their friends while they're at home and going about their daily lives. So yeah, I think those are the two biggest changes that I've noticed.
