My parents are two people I know who have aged exceptionally well. I say this because:
我認為我的父母是我所認識的人中保養(yǎng)的格外好的，我這樣說是因為：

They look almost exactly the same today as they did 25 years ago (as evidenced by the 2 pictures below)
他們現(xiàn)在看起來和25年前幾乎一樣（下面提供兩張照片證明）

They have no illnesses (like diabetes and hypertension) that require medication.
他們沒有什么需要藥物治療的疾?。ㄏ裉悄虿『透哐獕海?。

Neither have white hair yet! (At the age of fifty)
兩個人都還沒有白頭發(fā)?。?0歲了）

Eyesight pretty much intact!
視力都沒有減退！

(The first picture is today. The second is from twenty five years ago)
（第一張照片是現(xiàn)在的，第二張是25年前的）

All this isn’t a coincidence because they both work pretty hard on their health. Here are some interesting things I’ve observed:
所有這些都不是巧合因為他們倆都很注重健康，下面就是一些我注意到的趣事：

Once I woke up from my sleep in the dead of night to find my dad pacing up and down in the living room. Concerned, I asked him if anything was wrong. He said he was trying to finish the day’s 10,000 steps.
一次我半夜醒來發(fā)現(xiàn)爸爸在客廳來回踱步，我很擔心地問他怎么了，他說正在努力完成當天的10,000步的目標。

Both my parents eat very, very healthy. I have been asked more than once how my packed lunch could be green everyday.
父母的飲食都特別特別健康。曾經(jīng)不止一次有人問我我?guī)У奈绮驮趺疵刻於际蔷G色的。

My mother never misses her morning walk. She’s actually the one nagging my dad to get out of bed and walk everyday!
媽媽早上散步從未耽誤過，其實每天她都是把我爸爸從床上嘮叨下來去散步。

My father has actually refused to eat his own birthday cake (but this is just showing off! I think he was trying to make us eat healthier by example)
我爸爸真的拒絕過吃自己的生日蛋糕（但這只是為了炫耀！我認為他是為了向我們示范飲食要更健康）

They don’t eat between meals. They are vegetarian. They barely ever eat out.
他們兩頓飯之間不吃東西，他倆都是素食者，幾乎不出去吃。

The bottomline is they work very, very hard.
最后就是他們工作非常非常努力。

These are my own observations. I decided to ask them and see what additional tips they give.
這些都是我自己注意到的，我決定去問問他們，看看他們能不能給點額外的建議。

My mother said it is sleep (8 hours everyday). Fair enough.
媽媽說是睡眠足夠好（每天8小時）。

Why do older people have trouble walking and, in more severe cases, begin to fall because their bodies are too weak?
為什么老年人走路困難，更嚴重的還會開始摔倒？因為他們的身體太虛弱了。

The older you get, the more muscle you lose. It’s called sarcopenia. According to one study.
年齡越大，損失的肌肉越多。一項研究表明，這叫作“肌少癥”。

Is there a way to prevent it?
有沒有預防的方法呢？

Yep. Bodybuilding.
有，健身。

Picking up weights and moving a few dozen times will prevent, and even reverse Sarcopenia.
增重或移動數(shù)十次將能預防甚至使肌少癥逆轉(zhuǎn)。

So if you want to be able to walk when you’re 70 years old, get a gym membership.
所以如果你想在70歲時還能走路，去健身房辦個會員吧。
