I rode in my teens and early 20's. Almost bought a bike when I moved out here but decided the drivers were so awful that despite my efforts I would eat it some day.
Having said that there is nothing like a bike, and in your situation I would do it. Just remember reflexes and other things slow down.
My business partner who is in his 60's is having the urge to get a bike. Since he never rode I urging him not do.
