Riddle-d With Fatigue

Q: What does a tricycle and my wellbeing have in common?

A: When it comes to the bottom of it, it's tired, tired, tired.

My routine for the past three days:
1. Get up and eat breakfast
2. Go to the gym for a light, non-intensive workout.
3. Come home and lay and eat in bed (under an electric blanket) for the rest of the day.
4. Shower and call it a night.

Seriously. I'm always so cold and tired I can barely walk across the room to go on-line. Sorry if I haven't replied to your e-mail.

Perhaps it's better to call me. At least the cell phone is near the bed.
