Why would you be worried about what other people say or think about a backrest on YOUR BIKE?! There are a couple of options out there for backrests. If you want one then get one, if not then don't. Either way your comfort should be what's important in the end, not opinions.
Not sure what age has to do with comfort.....some folks like/love a back rest some don't ...thats what makes the world turn....if you are talking about passengers.....I would not have a passenger w/o a back rest...for their comfort and the fact I don't like people touching me while riding, We should be very concerned that our passengers feel safe and enjoy riding with us......the passenger back rest was an issue with my wife as she does have some back issues and the stock butt chock was not working...which prompted a new back rest riser...

For the first 35 years of riding motorcycles I thought why the heck use a windshield when bikes are all about feeling the wind on your face. At 65 I still like the feel of wind on my face when I ride my 1975 CB750 café racer. When I rode my Wing from Texas to Alaska a windshield sure was a joy. When I travel I make a backrest out of a touring bag, its nice to lean back for a stretch.
Bottom line, whatever floats your boat.
I would not mind seeing what the driver back rest looks like and how it mounts.
