Why do old white people always have bruises everywhere?

Older people have been living longer and their veins have gotten more... for lack of a better word--brittle. Hence why they bruise easier than the younger population. However, bruising can occur for more reasons than just falling over and hitting themselves on that sharp object that apparently did not cut them in the process. Also, keep in mind, how easy it is for bruising to occur... varies.

Hahahah, I know alot of people develop "liver patches" brown marks on the skin but I do not see many covered in "bruises". Perhaps Google liver patches if you don't already know what they are and if you do my apologies.

Older people bruise easily, and it would be more obvious on someone of lighter skin.

Maybe because white skin is paler so bruises are much more visible when they happen and also they are more likely to develop bruises than younger people

While lots of white people sometimes have bruises in some places it is absolutely not true that they "always have bruises everywhere". It's simply not true at all.

They don't all have bruises everywhere some do.

Bruises show up more easily on fair skinned people than they do on darker skinned people. Older people in general fall over and bruise easier than younger people.
