After dreaming of going with my truelove to Bristol Virginia toward the end of July 1927, or Spray NC any time between about 1925 and May 1931, I remember the couple of little pills I take every day which wouldn't be invented for another 60 years or so, and give thanks that I am right here when I am.

Of course, traveling with Louis Wu through Known Space would probably mean they would have medicines that would cure my chronic conditions once and for all, but I wonder if I would be the equivalent of a red-shirt-wearing ensign on the Enterprise.

As Oscar Otter said at the end of the eponymous book "I am happy right here where I am."
