@houston13 @patti14 I don't think I could say it better than @houston13 just did. When my aneurysm was at 4.1, I was blissfully ignorant and doing things that, in retrospect, were probably not very aneurysm-healthy... like crossfit! I was also traveling internationally extensively at that time and had no issues.

I had my aneurysm fixed when it was at 5.3cm so you've got a ways to go before surgery. Enjoy your life, try to keep your blood pressure in check, stay in shape and be cognizant but not obsessed. Surgery is a bear but I am 2+ years past mine and doing great... I hike and bike regularly here in the Rocky Mountains...
