The Guinness Book of World Records describes Ranulph Fiennes as the world's greatest living explorer. His expeditions include the first polar circumnavigation of the Earth and the first unsupported crossing of the Antarctic continent on foot. He has been up the White Nile in a hovercraft, and parachuted onto Europe's highest glacier. An obsession with diet and fitness comes with the territory, and for years Fiennes has fine-tuned his body to cope with the most inhospitable of environments and the most stressful situations of physical hell. So when I read vegetables and reduced levels of saturated fat helps prevent obesity and stops fatty deposits forming in the arteries and blocking them. Smoking, incidentally, has the opposite effect, as nicotine increases the heart rate and makes the blood clot more easily. Exercise is highly beneficial as it reduces both the pulse rate and blood pressure so minimising strain on the heart as it pumps blood round the body. It also helps an unhealthy obsession could have had an effect, or there may be so genetic predisposition and an event could have made it worse,' says Almond. 'We haven't done enough research in this area.'

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
