You're 70 and thinking about three wheels, then it's a good time to pull the trigger and see what's it's all about riding on three. You will enjoy the experience and not look back, especially with the copilot on the pillion. You will notice more 'bumps in the road' as one comment mentions, but that's OK, it's the nature of the beast and ya can't miss many holes with three wheels. Yes, more effort in the twisties, no question, but that's offset by the pure pleasure of the ride and able to enjoy the scenery more. You can get more 'stuff' on board, pull a trailer, or like some of us, get a receiver on the conversion, just do a slide in rack and and tie a water proof high viz bag on the rack. More stuff equals a happy wife at the end of the day.

I just turned 70 as well, and my wife and I ride a 2006 GL1800. Been riding since I was 16, got my first Gold Wing in 1984 and have been riding them ever since. I'm pretty sure I'm to the point now where I'm going to have to give up trying to keep this 900 pound bike upright in parking lots and such. Not only am I older now, but I'm weaker as well. Time marches on and takes its toll.
I've been putting off getting the Gold Wing triked because I just hate to give up the unique feeling of riding on two wheels. On the other hand I just don't feel as capable on two wheels with 2-up and loaded bags as I did just a few years ago.
Glad I found this thread and read how happy people are after having made the change from two wheels to three.
Guess I've gotta sell off a bike or two from the stable to pay for the trike kit now!
