Today’s air travel is hectic enough without crazy antics by passengers making it worse for other flyers. It seems to be in the news all the time. Recently, a woman passenger ran up and down the aisles threatening to kill everyone. Another happened when an already soused passenger got violent when the attendant refused to give him a drink.

Statistics indicate the situation is reaching shocking levels as air travel gets more and more stressful. The International Air Transport Association (IATA) reports a 50% rise this year for bad in-flight actions, including verbal abuse, sudden anger and actual injury-threatening scenarios.

Even in 2018, some of the most significant relics of American history won’t cost you money to admire.  At Philadelphia's Liberty Bell Center, you’ll get close to the famous ringer, with Independence Hall just a short walk away. While there, watch the 10-minute presentation about the Bell’s history, including how the famous crack happened.

Away from the busy, crowded, snooty resorts is the Artist Residence in the city’s Pimlico area. It has ten snuggly bedrooms, and the decor inside will take you back to your earlier days.

Entrance is through a striped awning, and inside the halls and rooms are full of paintings, posters and 1920s furniture. Play ping pong in the basement and also enjoy cocktails, breakfast and Sunday brunch there. Rates from $200. artistsresidencelondon.co.uk

When we hit age 65, most of us are still in good enough shape to handle all the physical requirements of post-retirement travel. We can ride the camel in Egypt, bike along Monaco’s championship trails and swim with the dolphins in Acapulco.

However, the inevitable aging process slows us down in the next decade, and in the next and so on. Therefore, while you still can do it all and have the time, book that intercontinental flight to Singapore, go aboard a luxury liner to Spain and bask on the tropical beaches of Bermuda. The old saying is you only live once. Well, if you do it right, once is enough if you’ve spent those retirement years exploring the wonderful world around you.
