A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria: * Has not undergone a hysterectomy or bilateral oophorectomy; or * Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months) * Women of childbearing potential in sexual relationships with men must use an acceptable method of contraception from 30 days prior to enrollment until 4 weeks after completing study visits. Males must agree to avoid impregnation of women during and for four weeks after completing study visits through use of an acceptable method of contraception. * Note: Includes, but is not limited to, barrier with additional spermicidal foam or jelly, intrauterine device, hormonal contraception (started at least 30 days prior to study enrollment), intercourse with men who underwent vasectomy. Inclusion Criteria: Younger Adults aged 18-35 (No intervention) * Free overt chronic disease Exclusion Criteria: * Pregnancy or breastfeeding * Heart disease * Cerebrovascular disease * Cancer or less than 5 years in remission * Chronic respiratory disease * Chronic liver disease * Diabetes * Alzheimer's * Chronic kidney disease * For those undergoing muscle biopsy: problems with bleeding, on medication that prolongs bleeding time * Taking azathioprine (Imuran), cyclosporine (Gengraf, Neoral, Sandimmune), dexamethasone (Decadron, Dexpak), methotrexate (Rheumatrex, Trexall), prednisolone (Orapred, Pediapred, Prelone), prednisone (Sterapred), sirolimus (Rapamune), and tacrolimus (Prograf) or other medications proposed to lower the immune system. Daily use of high potency topical corticosteroids used on greater than or equal to 10% of body surface area will not be eligible. Nasal sprays or inhaled corticosteroids will be reviewed on a case-by-case basis. * Taking strong or moderate CYP3A4 and/or P-glycoprotein (PgP) inhibitors * Taking strong CYP3A4 activators * Taking daily NSAIDs with the exception of baby asprin (81 mg) * Subjects who are not willing to restrict the use of grapefruit, grapefruit juice, and other foods that are known to inhibit cytochrome P450 and PgP activity and may increase everolimus exposures and should be avoided during treatment * Subjects who are not willing to restrict the use of St. John's Wort (Hypericum perforatum) because it may decrease everolimus exposure unpredictably * Subjects who are not willing to avoid blood donations 8 weeks prior to the first visit and 8 weeks after the last visit * For those undergoing MRI, contraindications with MRI which could include metal on your body * Low white-blood cell count (\<4,000 cell/µL) * History of stomatitis or ulcers in the mouth * Those on glucose lowering drugs * Participating in intensive exercise training program (high to moderate intensity exercise greater than 150 minutes per week) or planning to start new exercise program during study period * Tobacco use * Allergies to lidocaine or everolimus * Subjects currently enrolled in other clinical trials. Subjects may be eligible after a washout period that will be reviewed on a case by case basis. * Individuals with limited English proficiency * Subjects who are planning to have elective surgery 12 weeks prior to or during the intervention
