最近觉得脑子越来越不好使，表现症状是：根本记不住事，什么事一扭头就忘了，有点稀里糊涂的，经常误事。

I have found that my mind is not very clear these days. The symptom is that I cannot remember things and that I often forget what has just happened. I am sometimes muddleheaded and bungling things.

但若有新的且更好的捕鼠器又为什么不用呢？尤其是当我们极其需要而旧的又相当不好使的时候。

But if a new and better mousetrap comes along, why not use it, especially given how poorly the old one performed when we needed it most?
