Question: In July 2007, American business magnate and investor Warren Buffett's holding company Berkshire Hathaway bought an Israeli company, Iscar, its first non-U.S. acquisition, for $4 billion. Since the 1970s, Israel has received military aid from the United States, as well as economic assistance in the form of loan guarantees, which now account for roughly half of Israel's external debt.

Question: Gautama first went to study with famous religious teachers of the day, and mastered the meditative attainments they taught. But he found that they did not provide a permanent end to suffering, so he continued his quest. He next attempted an extreme asceticism, which was a religious pursuit common among the śramaṇas, a religious culture distinct from the Vedic one. Gautama underwent prolonged fasting, breath-holding, and exposure to pain. He almost starved himself to death in the process. He realized that he had taken this kind of practice to its limit, and had not put an end to suffering. So in a pivotal moment he accepted milk and rice from a village girl and changed his approach. He devoted himself to anapanasati meditation, through which he discovered what Buddhists call the Middle Way (Skt. madhyamā-pratipad): a path of moderation between the extremes of self-indulgence and self-mortification.[web 2][web 3]
Is there an answer to this question: What almost killed Gautama in his pursuit?

Answer: asceticism
