Not YouTube videos but yes, if I'm addicted to some series then I would just binge watch and watch them till 5: 00 in the morning.

我不会熬夜看YouTube视频，不过如果我迷恋某部电视剧，那我会一直看，可能会看到凌晨五点。

I had watched and watched, and nothing happened; and somehow my vigilance relaxed when I found nothing was likely to take place in the star'.

我看了又看， 什么也没发生； 当我发现这颗恒星上可能没有任何事情发生时， 我的警惕性不知何故放松了。
