Sigrid concludes this "personal journey into the unknown" with optimism about harnessing creativity in order to live a more fulfilling life with Alzheimer's even though it might not slow it down. We have to live in the present!

A year has gone by and Sigrid is back in Tacoma to spend time with her sister, Sylvia. Things have changed quite a bit, and Sigrid shows us Sylvia's new setup.

The two sisters talk about how important singing was for them growing up and Sylvia sings a little bit, too. This is their final appearance together on video before Sigrid's departure the next day.

Sigrid and Sylvia converse in the kitchen over coffee. They talk about coffee, about the city of Tacoma, about their month together, and about what they see out the window. Sylvia enjoys making sound effects with her voice every now and then.

Sigrid and Sylvia continue to work on making coffee. Meanwhile, they talk about what time of day they like to drink it and what they put in it.

Sigrid and her sister Sylvia hang out in the kitchen talking about coffee and making some, too. At times, they get a bit silly.

The two sisters talk about coloring, one of Sylvia's favorite things to do and they look at some of the work she has done.

The two sisters unpack a box that hadn't been opened since she moved to the house in Tacoma. It contains artwork she had done in the past along with some stray art supplies.

Sylvia talks about how her diagnosis was reached and about what limitations there are for her now, such as going out for walks by herself and singing in the choir at church.

Sylvia is willing to talk about her Alzheimer's diagnosis, even though she struggles to form sentences and find the right words.

Sigrid describes traveling from her home in Italy to Tacoma, Washington in the United States to care for her sister with Alzheimer's disease. She stayed there for a whole month.

Finally home! Sigrid talks about her trip home and how it feels to be back after a month away.

For the final days of Sigrid's visit to the New York area, she leaves the rocky North Shore and goes south to a place she knows very well from her childhood—the beach! It's a nice place to visit even in the cooler weather.

Let's look at how Long Island was formed around 20,000 years ago. It has to do with a glacier that brought plenty of material along with it and left some behind when it receded.

We're back on Long Island, exploring the North Shore with an outing to a wildlife refuge on one of the necks, or small peninsulas that jut into the Long Island Sound, the body of water separating Long Island from Connecticut.
