Being an adult I do attempt to hold down the gaseous emissions when in public, but it gets harder as you age. I swear when you hit 50 everything you eat or drink seems to turn to methane immediately.
I have noticed the same thing happening to me since I hit 50, in public or at work what I do is what I've seen our dogs do, I just ignore it, act like nothing happened. I won't say nobody's noticed, just that nobody's said anything, probably because there's 6 of us in the office and it would be hard to tell for sure who did the deed.
