I suggest that your uncle talk to a financial expert or financial advisor to help develop a long-term investment plan that fits the needs and purpose. They can help choose the right investment and regulate diverse investment portfolios so that risk can be managed and investment returns can be optimized.
In addition, it is very important to teach our children about the importance of planning long-term finances and how to manage money wisely. By learning about investment and financial management as early as possible, they will get used to and able to take intelligent financial decisions in the future. I salute your uncle who is enthusiastic and hard worker in his youth.
During this situation - I don't think we will get old - war, diseases and other calamities are taking the life of people so much
One should always ask God for the health and blessing
