Disturbing thought of the week

Question:

What impact, if any, do you think my moving back home and staying up late has on my parents' sex life? Dad is 49 and mom is 45. It's supposed to be great times for them, right, with the Viagra and whatnot?

I am launching a full investigation on this issue. Results to come at a later date.

Edit: this question was not supposed to have any type of Oedipean implications. The inquiry is based on the proximity between the rooms in our household, difference in sleeping patterns, and such considerations.
