Hello You are 63 years ,healthy and want to empty bladder . If you are male then such frequent urination may be due to enlarged prostate , so get in ultrasound of prostate and if it enlarged , you have to take treatment for this. Avoid fluid after 6 pm ( if possible ) and empty bladder at the time of sleep ( before sleep ) . Also get in blood examination for sugar level and deal accordingly. Urinary tract infection ( low grade ) is another cause of urge of urination. However , there are other so many reasons like tension ,anxiety but at the age of 63 years consult a surgeon or physician and get his opinion because physical as well clinical examination is important. Good luck.
