虽然从来没打过网球，也没看过完整的网球比赛，但是我觉得网球这项运动区别于其它运动最特别的一点是：一旦运动员上场比赛，中间就不能再获得教练的帮助，要自己独自面对场上发生的一切情况。所以李娜的自传书名是《独自上场》。
实际上，不止于网球，很多事情上我们都是“孤独”的，需要随时做好“独自上场”的准备。“独自上场”，才是生活的常态。
前几年听过张潇雨的播客《网球（上）——孤独和它所创造的》，专门介绍网球这项运动，这次奥运会想起来这期节目，只可惜好像这期节目没有下半段了。
这期播客里提到的《The Inner Game of Tennis》（中文《身心合一的奇迹力量》），多抓鱼上一直买不到。

In many cases, the content resembled that of the marketplaces found on the dark web, a group of hidden websites that are popular among hackers and accessed using specific anonymising software.“We have recently been witnessing a 100 per cent-plus rise in Telegram usage by cybercriminals,” said Tal Samra, cyber threat analyst at Cyberint.The rise in nefarious activity comes as users flocked to the encrypted chat app earlier this year after changes to the privacy policy of Facebook-owned rival WhatsApp prompted many to seek out alternatives.
“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
