May I suggest that Mr Wu Chun may like to look into switching to a more plant based diet for your elderly dad and family to help support and sustain a more physically and emotionally healthier life especially nowadays with many more kinds of new diseases manifesting; and to consider to help promote a more environmentally friendly living to sustain Mother Earth's already degenerating resources and all her residents not just only for this lifetime but also for your children and their family's future as well as the future generations. With your fame, wealth and success, you and your family could also help inspire many, many others to switch to a more plant based diet and doing their bit to help sustain Mother Earth to last a little longer. Thank you.
