I Am Age 65 In Great Health And Take No

I am age 65 in great health and take no meds. no weight issues and excercise daily . I do drink 5 beers per day and have done so for 30 years.
Lately I have had the very "urgent" need to pee and have some leakage from time to time. I have regular check ups with no indication of prostate issues urine flow is pretty good not forced. Having said that I get up from bed as many as five times a night and could pee as many as 15-20 times in a day. I also show no signs of diabetes but I may be beginning to have a thyroid issue. thoughts? Cheers.
