尊敬的老师：
  您好！
  打扰您了，我是南京理工大学博士生吴小兰，前期我们根据科学网博主的“研究方向”进行了博主学科跨度的一些研究，现想通过博主的问卷来对结果进行检验，非常希望您在百忙之中抽空填写一下（共9小题，约2分钟时间）问卷地址为 https://www.wjx.cn/jq/21238770.aspx ，本人将不甚感激。另外，我们郑重承诺：尊重隐私，所收集数据只用于学术研究，不外泄或作商业用途。

My right eyesight was 'none' for about a year from March 2016 - Jan. 2017 Retina detachment, out of the blue. Undergone PP vitrectomy surgery. Due to financial hardship, I waited a year to have cataract surgery. Now my eyesight is back but $400 add-on procedure to correct astigmatism resulted in over-correction by my own judgement. There's a film 'Something God made' about John Hopkins two heart surgeons that develop procedure to operate on infant with heart defects. I wrote a poem 'Eye witness'. I think I can post it here as a blog. Thanks for writing diaries and blogs for the past 60 years!
