As we appear to be getting older with the passing of time, we must keep in mind that our internal organs are aging as well. I'll be 58 next month. I often give myself a pat on the back for doing what it takes to keep diseases, sickness, ailments, and viruses away. It's hard work, diligence, and attention to details in keeping it muscular, tight, and streamlined.
I sometimes have a love hate relationship with myself when it comes to my diet and exercising, but when I think of that dreaded Alzheimer's disease or diabetes, I shake the thoughts off and run another mile or do another set.
Yes, I do sometimes get those 'old man' aches and pains.
