daily activities for folks that have PFTs in 30's and 40's?

I was just wondering what you all do in your daily lives when your PFTs start hitting the 30-40 percentile? Mine have dropped in this area and have finally had to step away from work because I am just to exhausted, so would love to hear what daily activities you guys do if you could share.
