Many of us remember solo traveling when we were young. Even without language facility, there were always other English speaking travelers around, both North American and Northern European. Being young and mostly unemcumbered, these other travelers were often open to casual social encounters.
Not necesarily true when you are 50+. For one thing, most of similar aged people are traveling with spouses or long time friends, or are in tours themselves. I'll take a boring companion over no companion at all when I am away from home and familiar surrounds for a long time.
Anyway, "boring" is a complex determination.
People of the host country, particularly European countries that see more than enough travelers may not be overly eager to get to know some random typically unstylish American tourist.
