"Always on" displays on smartphones are great. These are referred to as ...LED (different technologies of active LED screens - AMOLED for example). They have no backlight, just an array of LEDs. Power is only consumed by LEDs that are turned on. This allows them to be used to display the time (for example) whenever the screen is exposed (no need if it's in a case). Even if the phone has been sitting, untouched, for an hour, you can glance at it to see the time. My Pixel 2 lock screen also displays notifications - email, text, etc. Older phones blinked a separate LED to let you know that there was email, etc. But you had to look at the phone for a few seconds to see the blink. With the Pixel 2 the notifications do not blink, so a quick glance lets you see any notifications. This is a huge improvement in usability. Note that many phones now have always on displays - iPhone X, Samsung S9 (and some of Samsung's older models), others. This feature is worth searching for.
Apple AirPods - wireless smartphone earphones. I covered these in a previous post. They are great.
Einsky Wide Brim Sun Hat - UPF 50+, 3.7 inch stiff brim, ventilated top. Unlike the last time I looked for a good sunhat (many years ago) there are many nice sunhats listed on Amazon. This one fits my requirements and works well.
While looking at sunhats, Amazon "also viewed" (or maybe "also bought") showed sunblock t-shirts - Hanes Men's Long Sleeve Cool Dri T-Shirt - UPF (Ultraviolet Protection Factor) 50+ (>98% blocked). Many years ago, I got some long sleeve t-shirts for a trip to Florida. I made the mistake of getting my usual medium, cotton. These are useful in bright sun, but almost impossible to take off after sweating, and the style that I got had tight wrist cuffs. And I don't know the UPF as it isn't advertised for cotton shirts. This time I chose large, better ventilation and easier to get off. These are nice. The polyester feels nice. The wrists cuffs do not squeeze. A big improvement for a walk in the sun. And I can remove it after the walk.
Speaking of "also viewed", Amazon's product search often fails to find what I am looking for, but the "also viewed" section has it. Why didn't the original search find it? Regardless, "also viewed" is very useful.
Nimbus Microfine Toothbrush regular size (extra soft). These are great. Better than the Dr. Collins Perio Toothbrush that I was using. Look for them on Amazon.
