That makes sense. I've also noticed my hair feels weaker lately.

这很有道理，我最近还发现我的发质变差了。

So a lot of it just comes down to grunt work.

所以变形成质变。

So quality comes out of quantity.

也就是，变会引起质变。

What is quantitatively small can be qualitatively large.

变虽小，质变可大。

I tend to be very self-critical, but I do think that quantity leads to quality for some people.

我倾向于非常自我批评，但我也认为对于某些人，变可以引起质变。

If you're not drinking enough water or eating foods with vitamins, that could definitely make you look more tired.

我觉得是因为我没睡好。我总是熬夜刷社交媒体，刷完之后就很难入睡了。噢，不得呢！手机发出的蓝光会影响你的睡眠。是的，我在哪儿看到过，蓝光会阻碍你的大脑分泌褪黑，这有助入睡。这很有趣，我不知道会这么严重。确实很严重！ 而且睡不好不仅会影响你的精力。它还会让你的皮肤看起暗淡无光，产生黑眼圈，事实上，我曾读过一位皮肤科医生的文章，他睡眠不足会减缓皮肤的修复过程。这很有道理，我最近还发现我的发质变差了。睡眠不足也会影响发质吗？当然会。睡眠不足会降低你的身体产生角蛋白的能力，而角蛋白对头发健康至关重要。好吧，所以睡眠不足肯定是一个问题。但你觉得我的饮食也可能是原因之一吗？当然，如果你没有喝足够的水或吃富含维生的食物，那肯定会让你看起更累。

The AI systems are not close to being able to do the kind of AI research that would make qualitative changes.

人工智能系统尚未具备进行那能够带质变的人工智能研究的能力。

So it's hard to see them even with some free, some cap space signing of that kind of difference, making player and free agency.

因此，即便底特律拥有一定的自由球员名额和薪资空间，要签下那能带质变的关键球员并吸引自由球员加盟，依然显得困难重重。

You know, the Americans think about it really as a revolution in quality, but Canadians think of it as, no, it's a return to the Americans of the rights of the British.

你知道，美国人将其视为一场质变性的革命，而加拿大人则认为，不，这是将英国人的权利归还给美国人。
