What is time? We treat it as obvious knowledge, yet we lack a solid answer. We define units of time, measure time, but we cannot manipulate time. In contemporary physics, time may be unified with space into spacetime, but it's definitely not akin to the spatial dimensions.
I'm now 22. I'll never be 21 again.
What's life? Why am I here? Should I do something before I turn 23? 24? Age, and hence time, scare me. We're so helpless: Tick. Tick. Tick...
I like how this Enka song captures life and time. It sets a deep and mildly melancholic mood apt for reflection. Enka tends to do this kind of thing very well.
川の流れのように (trans. "Like how the river flows") by 美空ひばり
ああ 川の流れのように ゆるやかに
ああ 川の流れのように とめどなく
I'll translate it and find an mp3 soon.
