I am amazed that your MIL has adapted to use of a laptop and many very useful functions. So she has utilized various personality characteristics (stubbornness which in many ways is the disguise for her control) despite how she misses outside opportunities. To her, maybe, going to ‘the outside world’ - she is protecting her own level of happiness because it would make her sad on what she is missing on all the other days and times she can no longer be ‘out and about’ on her own.
Not having a TV or telephone. Well she has not found the need. She is living the life she wants, and seems to have the balance in life that she wants.
DH’s mom’s side has had moderate longevity – her parents born in 1887 and 1890, lived to 74 and 83 (dad died in 1961 and mom died in 1974); this granddad farmed and had two side businesses, a cheese factory and also repaired farm implements (they had 13 children – a 14th child died within 2 months --born 1933, and a 15th child was a still birth, in 1936). DH’s Mom and living siblings born between 1914 and 1931. DH’s mom was the youngest girl. His mom’s 5 brothers: (one died with tree felling accident at age 38), lived to 58 (1970 and significant heart issues), 79, 82, 83, and 89. His mom’s sisters and she lived to: 77 (massive heart attack), 89 (had series of heart attacks over the years), 92, 92, 93, 93, 94, and 96. The 96 YO had Congestive Heart Failure and was not going to be able to tolerate more aggressive medical intervention - she had very good recovery from a stroke due to her work ethic with therapy. Mom and many of the sisters had cardiac issues and lived out what their body could. The modern medicines and treatments for cardiac helped with their longevity.
DH has a lot of longevity on his dad’s side of the family. Have more family lineage info on one track: GGGF died in 1866, but GGGM lived to 83 (died in 1917). Next generation, GGF died in 1939 at age 73, while GGM died in 1950 at age 85 - these parents and offspring lived in rough conditions during a smallpox epidemic and all survived – GF and siblings born between 1893 and 1910. 9 children - one boy died at age 1 1/2; one sister (the youngest of the siblings) died in 1977 at age 67. A brother (who was a priest, and the 3rd oldest of siblings) died at age 80 in 1977 of Prostate Cancer, and one sister (2nd oldest of the siblings) died at age 90 in 1985. GF (oldest of siblings) died at age 96 in 1990. The remaining 4 sisters died at ages 101, 105, 106, and 107. The sister that died at 105 navigated well in a wheel chair and lived independently after her 101 YO sister had died.
The sister that died at 106 was a few months from age 107 - and she was a Catholic nun, Sister Anne, with School Sisters of Notre Dame (and she was part of the ‘nun study’ on longevity). As this Chicago Tribune article states, she began a ministry/organization on Chicago’s West Side when she was 76 years old (in 1982) along with two other religious. The last time we saw her was at a wedding in 2002 (when she was 96) - she flew in, and it was really grand talking to her about her life’s adventures on that visit and prior visits (on her nun study interview clip, she sounds just like DH’s grandpa). In those last final years of her life, she would go around the health care center (skilled care) “and cheer up the old folks” – and she was the oldest one there…
