Sick again

The sore throat I had yesterday is full blown illness now. I barely have a voice and I'm coughing with a rattle in my chest. I stayed home from work and I'm not going to work out today. Yesterday when I tried to work out with my usual 50 minutes on the bike I could only do 10 minutes then 20 minutes then rest and another 20 minutes. I didn't even try to do weights. I just wanted to get home get dinner started, eat and go to bed.
