When a woman is undoubtedly flattered by a charming man, she experiences the symptoms of Marathonitis. Symptoms include uncontrollable smiling, giggling, nervousness, and many similar feelings related to flirting. There is no cure for Marathonitis. Once you have acquired Marathonitis, there is no turning back.
