an abundance of fish. but in recent years, he and thousands like him have been asking, where are they? this is the tonle sap, south east asia s largest freshwater lake. fish caught by communities here feed millions across cambodia. translation: these past few years, there is less and less i water and fewer and fewer fish. i didn t expect to get a lot of fish because when i felt the weight of the net, it was very light. i felt right around it and ijust couldn t feel many fish. if they were there, i would feel them splashing around. this is not the catch mi and his family need. this is all they have to eat for four or five days. so how difficult is it for you to earn a living byjust fishing? translation: when we were just married and we had no children, l it was ok. but now, we have children, and every day, i need to send them to school. every morning, i need around $5 to pay for school. and these days, i have no income. it s taken four or five days, and that s all i get. i h
this is uzbekistan. once part of the enormous soviet union, uzbekistan is a country of arid deserts, lush mountains and ancient cities. in its long history, it s been home to many civilisations, remnants of which can still be seen today. and now its more recent past is as much of a draw. i m starting myjourney here in tashkent, the biggest city in the whole of central asia. it s dynamic, full of young people with almost half under the age of 30 and it s booming. though wherever you look, you are reminded of its soviet past. so what s this impressive building? incredible. this is our circus. munis nur has been studying the unique blend of soviet and islamic architecture that tashkent is known for. after a massive earthquake in the 60s, the soviets rebuilt the whole city. at that time, as you know, many different architects came from the soviet union, and all the architects tried to build the ideal city here. the circus is one of the many examples of the era s modernist arc
and the things some people will do to stay young! push it out, push it out. you got this. do you consider yourself a guinea pig? no, i don t! i consider myself to be an explorer on the frontiers, trying to find out what s possible. tech entrepreneur bryanjohnson is spending millions trying to turn back time on his body. i refer to myself as a professional rejuvenation athlete. it s a new sport i want to create. i m not a bio hacker, i m not a health enthusiast, i am a professional rejuvenation athlete. i love it. working with a team of 30 scientists, his daily life is dictated by an extreme regime of fitness, diet, tablets, tracking and treatments. i m chronologically 45 years old. biologically, i am a few hundred ages. my left ear is 64. my fitness test say i m 18. my heart is 37. my diaphragm strength is 18. and i playfully say i m trying to become like an 18 year old. my son is 17 and so, i always tease him and say, when i grow younger, i want to be like you . where s he
when you look at the guidebook, or on travel websites, or in fact almost anything about azerbaijan, they all start by telling you the same thing azerbaijan is the land of fire! huge natural gas and oil deposits are so close to the surface that they cause these natural fires to spring out of the ground. fires which burned continuously for over 4,000 years were once common across azerbaijan, but this is now the last. right up here, it s really, really pretty hot right up to your face you can really sense it. the whole of my body is really, really hot. this is incredible! it s. .. ..beautiful and bewitching at the same time. 2,500 years ago, these fires enticed zoroastrian priests from persia, who considered them a divine miracle. no wonder people for thousands of years have pretty well worshipped at this, certainly felt spiritual about it. i do it s overwhelming. but, halfway through the 19th century, azerbaijan s natural wonders attracted a different but equally fervent
i m not scared yet, but i m thinking i m going to be. yes, absolutely. it s a stylish slow burner, as you can see, and intriguing, sets up the characters beautifully. and there s some dark comedy there, as i say, in the way that this woman is kind of paying tribute to her past and feeling a little bit guilty about what they ve done with the family farmhouse. they ve demolished it basically for this incredibly gleaming, modern home. and she and her husband are up to some pretty shifty business. and then kind of a lot of guilt comes out when she has memories of her mother. there s a lot about welsh folklore, about the land, about the environment, about our connection to the past, about the dangers of wealth and greed. there s also an element of the seven deadly sins in there. it becomes increasingly kind of dramatic when all four members of the family have dinner guests and things take a bit of a turn, to put it mildly. and it s nicely filmed, isn t it? it looks, visually, it
