In both cases, it's up to us now to discipline ourselves to avoid the fats in junk food, and the breaking news and dopamine thrill-ride of social media.

fertiliser, the challenge is more real, but there is still an important and obvious first step – eat less meat. A large part of the world’s agricultural system is dedicated to growing crops and vegetables to feed animals, which we then eat. Reduce the last part of this equation (i.e. eat less meat), and the huge inefficiencies in the system mean far less fertiliser is required.

Sergio: Did you ever work in the US?Rodolfo: Yeah, I worked all the time, I never stopped. One of the first jobs I had…My uncle worked at a restaurant called, Baker's Square in Chicago. It was on the corner of Tui and Pratt. I really, really, really wanted—I think I was in fifth or sixth grade—a phone. I wanted a phone, it’s called the Psychic Slide. Phones used to flip, but this one slides. I wasn't gonna ask my mom for it, so I asked my uncle. "Hey man, I know you work at Baker's Square and I know around the holiday season it gets really busy. Can I help you? Can I go?" He's like, "Well, yeah, if you want." I used to wake up like 3:00 in the morning, and I used to go and help him out. After that, I really liked making money and I really liked dressing nice, I liked having my nice haircut or whatever. My very, very first job was in Wilmette, Illinois. I was a caddie. Yeah, and then—Sergio: On the golf course?Rodolfo: On the golf course, yeah. Wilmette Golf Course actually. I remember I was always the first one there. They used to choose us, when everybody got there, "Okay, you come with me, you come with me." I used to always go there and there was a gentleman by the name of... Man, I forgot his name. Like the President, Gerald Ford, that was his name Gerald Ford! The only reason I remembered was because of the President. He used to always get there around the same time I got there. He finally asked me, "Do you want to be my personal caddie? I don't want you working anymore with all these other kids, because nobody wants to work. Do you want to be my personal caddie?" I'm like, "Yeah, absolutely." It was going really, really well and everything.Rodolfo: I got to high school, I had a number of jobs. I worked at Subway, I worked at Chili's, I worked at... What was it? Outback Steak House, but then I finally just got to the Cheesecake Factory, and that's where I stayed the remainder of my time. The remainder of my time I stayed there, and I started from the busboy and I finally ended up being a bartender. One of the head bartenders, one of the head servers, they used to pay-out people and everything. Obviously, I didn't have my social or anything, but I was a little bit older than what I really was. When I first got there, when I first, first started working I think I was like 14. Obviously you can't work that young, I think actually, I was 18, at 14.Rodolfo: I didn't see it as anything bad. I knew that if I got caught with my fake ID and my fake social security card I'd get in trouble, but that's why we're there, that's why we worked. I didn't get a fake ID to go party or go get into clubs or bars or anything. The main purpose of it was for me to be able to get a job, and so my mom wouldn't have to work all those hours that she used to work. She used to work at a Burger King, overnight. I used to barely see her, and I didn't want that anymore. I told her, "You don't have to work that much if I start working. We can help each other out, we can, we're a team.” It was only my mother and I until I turned 14, when she met my stepdad. All throughout that, it was just my mother and I.
