Chris Underhill was a social entrepreneur who dedicated 40 years to helping marginalized people in poorer countries. On a study trip, he saw mentally challenged children begging on the streets, which motivated him to establish organizations to help the less fortunate. In 2000, he founded Basic Needs, which uses a 5-pronged approach through community healthcare, livelihood programs, research, and collaboration to help over 657,000 people in countries like Ghana, Tanzania, India and China. The presenter was inspired by Underhill's dedication and participates in charitable projects through Boys Brigade, which have been both fulfilling and eye-opening experiences.
