Dates

I often use memorable dates as part of my password on the computer.  I was using 1922 as part on my password on my work computer which is the year my Dad was born.  Today I was sending an email to my supervisor with the list of days that I had worked in the past two weeks.  It was lucky that I proofread the email before I pushed Send because I had put 1922 as the year instead of 2018.
