Chest hair?!

If I had to pick one thing I would want added to the in-game features, that would be it. It may sound odd, but it's actually one of only two pieces of custom content I've allowed into my game, and the other was to fix a bug. Srsly, JOY.
The rest looks awesome, too. I'm happier than ever epic lifespan was included in the game from the beginning. Even with the possibility of aging down, our sims are going to need it to take full advantage of what life has to offer.
