Lifetime ni ngumu but I want firms that have solid corporate governance that has been tested over the years. Furthermore, the core product/service is something we will need for many more decades.
EABL - Alcohol has been around for millennia and isn't being replaced soon! EABL is almost 100 years old with a parent who has been around for centuries.
Bamburi - Cement (& its variations) have been around for centuries as well. The parent has a long history of corporate governance. The product remains relevant to us now & likely in the distant future.
Greedy when others are fearful. Very fearful when others are greedy - to paraphrase Warren Buffett
