I live in a country which fortunately gets Alphonso mangoes from India. On the few occasions I have offered it to uninitiated guests and colleagues (making sure they aren't allergic first), the reaction has been a wide eyed disbelief of how good this variety is. Of course there are other varieties that are good (Langda is a close second).
If you ever get a box at home, unless rules are set and respected, it quickly becomes a free for all and people who hate welding a knife or peeling a fruit quickly become adept at it.
It is that good.
On a separate note: we live in interesting times where I can almost have a culinary-credo like I want to try the amazing food each place has to offer. Someone needs to put a list of these things - fruits, dishes, what have you and we need a serious conversation about how some of us can sample them from far away.
1. People are far more likely to store and curate their vacation pictures than healthcare data. There is a behavioral aspect to this. There isn't a lot of 'feel good' attached to storing a good HDL/LDL reading. Quite the opposite when it's bad.
2. Most countries develop their own version of a EHR, sometimes controlled by patients. Success rates vary but they remain a very useful tool for managing chronic conditions and patient peri-operative journeys. Once governments (local or national level) take over, there is very little incentive for anyone to develop.
3. There have been many attempts to create a patient-led EHR by companies but it is difficult to get off the ground and sustain due to data ownership, security, sharing and commercial complexities.
4. Storing the data itself is trivial. FHIR covers this well and within haematology at least, the support for standardization is strong. LOINC, SNOMED and UCUM are well established. Just be careful to store the initial units and reference ranges.
5. My personal take is that personal EHRs will take off once a good open source p2p toolkit implements superb encryption-led access control across workflows with top institutions comes into play. This is unlikely because of how EMRs lock up provider data.
