Nice post, Jacques.  Luckily, I&#x27;m only 47.5.  I&#x27;ve got a long time before I have your concerns of being 50.<p>I&#x27;ve found that the hardest part of getting older is the work you have to put into your mind and body just to slow the decline of age.  You go from being in your 20&#x27;s and eating all the donuts and burgers you wanted to.... to being in your 30&#x27;s where you start having to watch what you eat and limit some portions... to being in your 40&#x27;s where now I&#x27;m pretty strict with what I eat and how much.  I hardly ever eat sugar or bread, much less the holy combination of the two in a donut.<p>One of the most disappointing aspects of getting older is my disillusionment with medical developments related to aging.  When I was in my 20&#x27;s, I thought that a lot of problems with aging would be solved within my lifetime.  Surely, I figured, by the time I was 50, they&#x27;d have eradicated cancer, cured baldness, and developed other general techniques for rejuvenating the mind and body.  No such luck, I guess.  The older I get and view medicine through the lense of how it can help me with various aging problems, the more I realize that medicine is really still in its infancy.  Medicine is fumbling around like the blind men feeling the elephant who don&#x27;t know what they&#x27;re touching.  At the rate things have been progressing, fundamental medical miracles aren&#x27;t years or decades away - they&#x27;re perhaps centuries away... but I hope to be proven wrong.<p>That said, there are things I enjoy about getting older, like watching my kids turn into young adults.  I hear that having grand-kids is fulfilling, although I hope to avoid that pleasure for at least another 10 years.
