Dear Drowning, I am 83 and started a new business in 2015, I was able to start it because the part time work in net work marketing.  I am a naturopathic doctor which does pay like an MD.  However net work marketing can be a trap, most of them have requirements that guarentee you to fail, they just want your investment.  I have found only one that pays you based solely on what you do.  It will take a little time to educate yourself about the products, and only requires a $40. starting cost, which also gives you $40. of product.  You can contact me for more info. Also you are still young, you are only limited by you.  The right attitude and the never give up go get um will get you there.
