A simple urine test all males can do:
Have a leak in the garden.
If ants gather around, you have diabetes.
If you piddle on your feet, you have prostate problems.
If it smells like a barbecue, you have cholesterol problems.
If your wrist hurts when you shake it after your finished, you have osteoarthritis.
If you leave the old fella out when you return to the house, you have alzheimers.
