"But Time, unfortunately, though it makes animals and vegetables bloom and fade with amazing punctuality, has no such simple effect upon the mind of man. The mind of man, moreover, works with equal strangeness upon the body of time. An hour, once it lodges in the queer element of the human spirit , may be stretched to fifty or a hundred times its clock length; on the other hand, an hour may be accurately represented on the timepiece of the mind by one second. This extraordinary discrepancy between time on the clock and time in the mind is less known than it should be and deserves fuller investigation. But the biographer, whose interests are, as we have said, highly restricted, must confine himself to one simple statement: when a man has reached the age of thirty, as Orlando now had, time when he is thinking becomes inordinately long; time when he is doing becomes inordinately short."
Virginia Woolf - Orlando
