Picture（画） this. You're 75 years old, and life looks pretty different nowadays（现今）. You, like 90% of other people your age have chosen to age at home, and things are different. You don't get out to run and ski as much as you used to, but you still get out every day for plenty of walks and bike rides with friends that live around you. You have a lot more doctor's appointments（任命） now, three to four a week, but it's not a problem because public transportation（运输） takes you directly（直接地） to them, and technology has gotten so advanced（先进的） it brings healthcare（ 卫生保健） directly（直接地） to your home. Speaking of technology, you once fought with it for hours on end, but today it's been built for you and your 70-year-old friends.

  It's changed your life, and it's even helped you find a part-time job that you have mentoring（[希神]门特(良师益友)） the next generation（一代） in the career you've spent 30, 40 years building. You're living out your golden（金色的） years, and they are truly（真实地） golden（金色的）. You've probably figured（ 认为） out by now that's not reality（现实）. That's not what it looks like for most 75 years old today if you're lucky enough to make it to that age, and the reality is a lot harsher（严厉的）. Every day in the U.S., 10,000 people turn 65. That's 3.6 million annually（年年）.

  Collectively, people over the age of 65 make up nearly 20% of the U.S. population. Soon they will outnumber（数目超过） individuals under the age of 18, and each one of them costs more to take care of than an individual under the age of 18. Cost is a major concern（关心）. Most of them won't be able to afford（担负得起…） long-term healthcare（ 卫生保健） or retirement（退休） communities if and when they decide they need one. And the government is already panicking because they know that by 2037, trust（信任） fund（资金） reserves（储备(物)） or social security will have run out, and they need to find new sources of funding（ 基金）.

  I believe there's an issue（问题） that's just as big as cost, though（ 虽然）, one we often ignore（不顾）, and that is loneliness（孤单）. One in four adults over the age of 65 today are considered lonely（孤独的） or socially（社交上） isolated（使隔离）. One in four. And when you're categorized（分类） into that bucket, your risk（风险） of all timers（[电子] 定时器） has just gone up by 50%. What comes with loneliness and social isolation（隔绝） is often depression（沮丧） and anxiety（焦虑）. Men over the age of 65 in the U.S.

  today have the highest overall（全面的） rate of suicide（自杀）. If this situation sounds dire（可怕的） and unsettling（ 使人不安的） to you, it's because it really is. And it's terrifying（ 恐怖的）. These are our loved ones, our family, friends, and we're letting them down. So what am I doing? I'm 29 years old.

  I'm standing up here lecturing you about what it's like（喜欢） to age. And no, I haven't retired（退下）, and I haven't cracked（裂缝） the secret to longevity（长命）. But a series of events started happening a number of months ago, and I just started paying attention. The first was when my mom was actually at my parents' home in San Diego, and she was out on a walk like she frequently（频繁地） does, and she took a fall. And the fall was pretty jarring（ 声音刺耳的） because it was going to take some time for her to recover（恢复）. And she's a very active person.

  So this changed what her life was going to look like for a little bit. But it was also jarring to me because society has conditioned me to believe that this is what happens as you start to age. You take more falls. The falls get riskier（危险的）. And what was our future going to look like?
