Next time you walk through the airport doors, garage or sidewalk, you won’t see them. But dozens of electronic eyes will be following every move, especially as you’re finally lined up at security when boarding your flight. And as the technology gets more and more advanced, those all-seeing eyes will not only scan your face and figure.

They’ll also be able to use that new info instantly to merge with stored visual impulses and texts about you. First, of course, is the search of face and/or figure to seek a match of those of known criminals. There’s particular emphasis on images that may have a history of terrorism or members of terrorist organizations.

Those who fit any of the images will be detained for more detailed security examination, and possible arrest. So, senior wanderer, next time you go into an airport, always wear an innocent smile and carry only approved stuff on you and in your baggage.

Enjoying cruise ships, resorts, casinos and other lush destinations often involves all-you-can-eat meals. Some seasoned travelers jump in and stuff themselves with many more calories than they normally consume.

Especially for older people with tender stomachs, it can be a bad idea, and turn a fun vacation into painful sickness. Additionally, gobbling up more than you eat in normal meals at home can cause medical problems, especially if you try unfamiliar dishes with exotic ingredients. Additionally, because buffet food sits on display for hours, spoilage can be potential for even more serious physical problems.

Therefore, when your journey involves tempting displays of all-you-can-scarf foods, take it easy on the amount you take, and be sure what you eat is fresh and clean. Also a helpful tip from your travel4seniors.com editor. At a buffet, instead of stuffing myself, I eat a modest amount. Wearing a coat with lots of pockets, I then wrap and sneak out with some choice foods for a later free midnight snack and/or next-day lunch.

Q: I need to fly frequently, but as I get older the ordeal becomes more and more uncomfortable, both physically and mentally. I still have another five years of frequent business travel before I retire. Any suggestions on how I can cope? MJMcC, Portland OR

A: Try meditation. Block out aircraft noise, confusion and discomfort. Look for local services that teach the ancient practice, and/or scan online meditation websites for instructions. There are also basic ways to pass the long flight time with smartphones and other portable electronics in your ears and eyes. Fill them with prerecorded books, music and videos. And don’t forget to bring a brimmed hat or cap you can pull down over your eyes to blot out the crowded, noisy aisles and seats around you.

When planning overnighter drives and flights with your pet, research onlline first to find a hotel/resort/motel that allows them. Then, when checking in, find out all the services and extra costs involved for your pet.

In some situations you may be required to keep your pet in a hotel kennel during your stay. Also, there may be added fees for pet services. On the bright side, there may be special activities provided to make your stay more enjoyable for both you and your furry companion.

For example, if your visit will be in downtown San Francisco, consider Hotel Nikko. First, there’s an official canine welcomer named Buster. For $10 a night your pet gets a doggie bed, toys, tennis ball, food bowl and leash. For more info, go to www.hotelnikkosf.com/pet-friendly-hotel
