As we age and experience the death of parents and peers, we become increasingly aware of our mortality. Such awareness may trigger anxiety and prompt preparations, such as writing wills and advance directives.
Not someone, but myself, unfortunately. The last flight I was on was my first time leaving town without my kids. The anxiety I got from leaving them and being a day's worth of traveling away made me feel physically sick. I knew we'd miss them and I knew it would be hard, but I'd generally been strong about it and despite that aspect, very excited. Once we got as far as boarding the plane, I was nauseous from anxiety.
