Textmeditation can fix this, and i dont think the explanation you quote tweeted in your reply that “each year is a smaller % of your life.” is the real explanation
time speeds up because experience gets compressed by habit, craving, aversion, planning, selfing. these create conditionings most people can't feel, but are there, and you can train to feel it
lsd is the obvious proof point: temporarily loosen the conditionings and ~everyone reports time slowing down, things being more vivid, the world feels childlike again. because it is more childlike, you had fewer conditionings then. almost everyone with tens of thousands of hours of meditation practice reports ~2-3x slower time, more vivid experience, because something drops, which matches my experience too (this longevity benefit was a big motivation for doing it in the first place, and it basically did what the books claimed it would)
