"au naturel". However, next week I am having knee replacement surgery and part of the protocol for getting ready is showering every night for a week with surgical scrub soap and then putting on clean pajamas, I guess to avoid rolling around in all the nasty bacterial in one's sheets. The idea being to reduce as much as possible the amount of bacteria one's skin and hopefully reduce the chance of infection of the wound. Owning none I had to buy two pairs of pajamas and I hate em. Can't wait until I'm swingin free again.
