My most embarrassing moment with a Trek actor was because of Stewart. I was at a con once. My fibro was bad, and I was tired, and just sitting in a chair outside the hotel out back people-watching in-between shows. Stewart came into view. He was wearing a black t-shirt and blue jeans, and must have been in-between events too, I guess. I stared a bit too long, partly due to fatigue and partly due to the idle thought that "damn, he looks good for being in his 80s." I meant nothing by it.
But he looked my way and caught me looking. I bet I turned crimson. I smiled, shrugged my shoulders in apology, and hastily looked away. Oops.
The man was in superb shape though. I had to give him credit. He took very good care of himself. He didn't look like he was as old as he was.
