Bess Truman, the wife of President Harry Truman, is the only first lady to have lived longer, according to the National First Ladies Library. (Bess Truman died in 1982, at 97.) Jimmy and Rosalynn were the longest-married presidential couple in U.S. history. The actress is asked about the politics of this matter, and the refusal of politicians to commit to attending such marches. Eventually the SOS team told Powell they could get a helicopter to him, but it would take four hours. “I’m going to be dead in four hours,” he remembers thinking. “In the end I just said to myself that I'd rather die falling down a cliff than sitting here,” he says. He examined the cliff and saw a few exposed tree roots to hold onto, so decided to make an attempt at climbing down, but fell 15ft (4.5m), slicing his nose open in the process. Liz Hirsh Naftali and Noa Naftali, the great aunt and cousin, respectively, of 4-year-old Abigail Idan, issued a statement Sunday following Abigail's release by Hamas. Adding rehydration salts without good volumes of water could help Powell to replace salts and sugar, but it also risked causing further negative imbalances in his body. In extreme cases an imbalance in salt levels can lead to seizures and even brain haemorrhage.

Although it may be safe to drink urine in the short term to rehydrate, the physiological response to dehydration is to conserve salt and water,” says Lobo. “Urine output decreases, and ultimately the human can develop acute kidney injury and anuria (where the kidneys fail to produce urine). Hence, the quantity of urine in the medium-term will not be enough to sustain adequate hydration.” On average, water makes up about 60- 70% of the human body, largely depending on your age. Our bodies lose water through our urine, sweat, faeces and breath, so we have to continually replace this by drinking and eating ( around a third of the water we consume comes from our food). If we don’t do this, our bodies can become dehydrated. Patterson has been helping her community adapt to the heat by planting varieties of heirloom tomatoes that are more resilient to fungi that spread more rapidly in warmer climates. We have successfully, in the last year, bought the numbers of people coming over here illegally down by a third," she said.

Patterson moved to her new community two years ago to help rebuild after a hurricane. She now gardens with her three-year-old and his wheelbarrow, and has seen the impacts of climate change in her Florida gardening community. While MPs are disciplined for swearing during debates, convention also bans them from calling their colleagues liars or accusing them of being drunk, among other things.

A newly updated government map has many of the nation's gardeners rushing online, Googling what new plants they can grow in their mostly warming regions. Setting off at 4am, Powell climbed out of the gorge with two-litre water bottles. He had been used to drinking straight out of the Zambezi, so didn’t foresee the need to carry any more than that. When he began walking it was already 48C (118F), and three hours later he made it out of the gorge, which he thinks was between 750m (2,475ft) and one kilometre of ascent. At this point, he had one water bottle left. But when he reached the top it was not what he expected. Rosalynn worked tirelessly in the bid to re-elect her husband to a second term in 1980 — a campaign Jimmy lost to Ronald Reagan, a former Hollywood star and governor of California who represented the ascendant conservative movement. When exercising in a hot environment, the human body can lose between 1.5-3 litres (2.6-5.3 pints) of water every hour due to sweat. Another 200-1,500ml (0.3-2.6 pints) can be lost as moisture in exhaled breath, depending on the humidity of the surrounding air.By this point I was starting to feel really ill,” he says. “I started to overheat, and my body temperature was just insane.” When our family was in the White House, every so often, Rosalynn would join me for lunch, offering a few words of advice and always — always — a helping hand,” Obama wrote. “She reminded me to make the role of First Lady my own, just like she did. I’ll always remain grateful for her support and her generosity.”
