Farts, etc.

My family tree drops its leaves
around 60, with any luck.
My middle age has brought me
eyes that water in the winter
so lovers tell me not to cry
and I protest that these tears
don't reveal my sadness.
There is an atmosphere
similar to an inner-ring planet
that floats around my stomach
Venus or something gaseous
I choose to hold it in or not
depending on who is near me
whom i want to impress
and how fast i am walking
