She moved to Arizona to escape what she thought were allergies. It didn’t work. She got married, and moved back to California and a doctor who she describes as her “Doctor House” diagnosed her with mast cell activation syndrome, an immune disorder where certain cells release too many chemicals.
婚后，她搬到加利福尼亚居住，一名她称为“豪斯医生”的外科医生诊断她患有肥大细胞活化综合征（mast cell activation syndrome），一种由于某些细胞分泌过多化学物质而导致的免疫系统的紊乱。
Today, for the first time in years, Hagberg Fisher is living without a diagnosis hanging over her. She’s on a strict plan to keep her mast cell activation in check and she says it’s working, and she feels better. But she still lives with uncertainty about her health. She’s never sure when she might be diagnosed again with a tumour, whether there’s something lurking within her waiting to finally reveal itself. But she says the uncertainty of her own life, and how long it might last, has completely changed her.
The day you will die
What if you knew when it would be?
Various online quizzes plot your death date using demographic data such as race, gender and age. According todeathclock.com, for example, a 28-year-old non-smoker like me, with a BMI under 25, will die on Monday, December 26, 2044. These websites wildly overpromise in their accuracy, but scientific tools for looking at what might kill a person – and when – are improving.
五花八门的在线测试通过人口统计数据，例如种族，性别和年龄来预测你的死亡时间。例如 deathclock 网站预测，像我这样的28岁的非吸烟者，体脂指数低于25，将会在2044年12月26日星期一死亡。这些网站严重的夸大他们的准确性，而一些用来预测人死亡的科学工具正在不断的改进。
Some life insurance companies, for example, try to predict lifespans of their users based on big data techniques. And researchers are searching for genetic clues to death dates. Certain genes might even help doctors predict the time of day you die. People with one genotype in a study at Harvard University died before 11am; others on average died just before 6pm.
For now, it’s mainly guesswork, based on averages – but as personalised medicine and genetic research advances, the date of your death may eventually be a fact that you must learn to live with.
Death on the mind
Scientists know that reflecting on death can influence our thinking in profound ways, often without us realising. Some research has shown that whenever any resource, like time left to live, is scarce, people tend to value it more. Another researcherhas found that when students write about death for a period of time, they report lower rates of depression and anxiety and higher levels of self-esteem and motivation.
