Within a month I have "retired" from the job I've held throughout the last 7 years of my 20's...am leaving my 20's and turning 30...and am having a baby for the first time.
But I can't have any alcohol, chocolate, or even a nice - relaxing - sauna in order to deal with these big changes.
And God forbid I don't get up at least 3 times a night to pee (thus, not being able to actually sleep through the night before I'm forced not-to).
So this is why women-folk got pregant earlier in the olden days...so they could turn 30 with the aid of alcohol & chocolate!
