It is disappointing that there are people who are unscrupulous and use the names of others to promote their products and services or to endorse their reputations. I just changed my password to my email account after being hacked. I wish it to be known that I do not endorse products (e.g., pharmaceuticals), services (e.g., airline bookings), or job opportunities and work at home for pay schemes. Unfortunately, I just finished a scholarly book on the history of sex determination and it will be going into production early next year. As a result of Googling documents I needed for this study, I have been flooded with invitations to hire sexual escorts, get blow jobs, or find sexual pen pals on the web,. At age 80 I desire none of these services. I will leave this Blog for the indefinite future so that if you happen to see me endorsing one of those out of character ads, you will know it is a fake.
