Thank you @Viswamitra ji! You have given a great foundation to your son and I am sure he understands the risks/benefits of the loan. I hope his patents are successful. If he is an inventor, I understand the spirit. I have a patent (academic so I didn't need to spend any money and the university gets most of the revenue it generates) so I get the thrill of inventing something new and wanting to patent it. "Simplicity and contentment result in extraordinary benefits in life." Such a powerful statement! Contentment is the key to happiness!
