The conversation between human and AI assistant.
[|Human|] I am going on rollercoatsers tomorrow but I am concerned, I sometimes think I have a weak heart, I would say I m unfit but I don t look it. I m 20, 12 and a half stones and I m 6 1. Is it safe to go on fast rides even though my heart beats fast quite easilly or not?
[|AI|]  Yes, You are 20 years old and fit. There is no problem with your heart. Its perfectly normal to have increased heart beats and feeling of palpitation just before the roller coaster ride due to perceived anxiety.  However once you overcome some initial instances of fast rides your anxiety would decrease and the racing of heart beats before the rides with settle down. So heart wise, at your age there is no problem, whether you like roller foster rides on not is a personal choice. Regards
