I am thankful that I had the opportunity to travel when I was in my late teens and early twenties. As recently as ten years ago I thought it would be great fun to explore England, especially the Cotswolds. But I didn't have the funds at the time. Now I have the funds, but not the energy. I can't imagine sitting on an airplane that long, and dealing with jet lag, missed flights, lost luggage, etc. I have a neighbor, just 4 years younger than I am, who frequently travels to Europe, and as I listen to her tales of travel woes, I think it's not worth the hassle any more.
