"I left after three years and went to work for an aerospace company back in New Jersey. I then had the opportunity to work with a manufacturer as a systems engineer, as well as with a smaller company as the vice president of a small division. At my final company, I served as vice president, and we had contracts with the Department of Defense."
"Aging isn't something that can be taken lightly. People say that age is nothing but a number. That's just simply not true. Anybody who says that has probably not seen their mom or dad age. I spent my career in the teaching and engineering fields I started my career as a classroom teacher in Newark, New Jersey, teaching secondary mathematics."
"I started substitute teaching, which I did from 2001 to 2005. I became a certified teacher and did that for the next 12 years, retiring in 2018. After I stopped teaching, I finished and published a book I'd been working on for some time, titled "A Newark Childhood." The book started as a tribute poem to my mother."
David Hugo Barrett, 82, works as a substitute teacher in Maryland and continues working despite two disabilities that affect his mobility because the extra income is necessary to pay his bills comfortably. He began his career teaching secondary mathematics in Newark, New Jersey, then moved into computing for an electric company in Massachusetts, working on missile guidance systems for US nuclear submarines. He later worked in aerospace and served as a systems engineer and vice president at manufacturing firms with Department of Defense contracts. He returned to substitute teaching from 2001 to 2005, became a certified teacher for twelve years, and retired in 2018. After retiring, he finished and published A Newark Childhood, which began as a tribute poem to his mother. Barrett emphasizes that aging should be taken seriously and is not merely a number.
