也許是這樣

3. To depress, as in spirits or health.

4. Informal To draw (money) as wages: pulls down a hefty salary.

And so with the sunshine and the great bursts of leaves growing on the trees, just as things grow in fast movies, I had that familiar conviction that life was beginning over again with the summer.

There was so much to read, for one thing, and so much fine health to be pulled down out of the young breath-giving air. I bought a dozen volumes on banking and credit and investment securities, and they stood on my shelf in red and gold like new money from the mint, promising to unfold the shining secrets that only Midas and Morgan and Maecenas knew. And I had the high intention of reading many other books besides. I was rather literary in college--one year I wrote a series of very solemn and obvious editorials for the "Yale News."--and now I was going to bring back all such things into my life and become again that most limited of all specialists, the "well-rounded man." This isn't just an epigram--life is much more successfully looked at from a single window, after all.
